AWS Durable Execution SDK - OpenTelemetry Plugin

OpenTelemetry instrumentation plugin for the AWS Durable Execution SDK for Python. Emits durable execution spans on one execution trace, with deterministic workflow, synthetic-root, and operation span IDs.

Features

• Shared Execution Trace: Workflow and Invocation spans share one trace, anchored to a propagated backend parent when available or a deterministic synthetic execution root otherwise
• Same-Trace Ambient Parenting: Invocation spans use the active ambient span only when it already belongs to the execution trace
• Span-per-Operation: Each durable operation (step, wait, invoke) gets its own span with accurate timing
• Continuation Spans: Operations completing in another invocation produce a new correlated span without fabricating an unobserved prior span context
• Log Correlation: Enrich application logs with trace ID and span ID for end-to-end observability
• Provider Integration: Use the global ADOT provider or supply an explicit SDK TracerProvider
• Execution Sampling: Resolve sampling once per invocation and apply it consistently to Workflow, Invocation, operation, and attempt spans

Installation

For an existing Core 2.x / OTel 1.x application, start with the Core 3.0 / OTel 2.0 migration guide.

When using an ADOT or community OpenTelemetry Lambda layer:

pip install aws-durable-execution-sdk-python-otel

The base package intentionally does not install OpenTelemetry libraries. The Lambda layer supplies a version-aligned API, SDK, exporter, and propagators, preventing packages in the function artifact from shadowing parts of the layer.

For an application that configures its own OpenTelemetry provider instead of using a Lambda layer:

pip install "aws-durable-execution-sdk-python-otel[standalone]"

The standalone extra installs the OpenTelemetry API, SDK, and AWS X-Ray propagator. The application remains responsible for configuring its provider, processors, and exporter.

Quick Start using X-Ray/CloudWatch Tracing

1. Add the ADOT Lambda Layer to your function and set AWS_LAMBDA_EXEC_WRAPPER=/opt/otel-instrument
2. Enable X-Ray Active Tracing on the function
3. Pass create_otel_plugin_factory(mode="invocation") to your handler's plugins list
4. Add X-Ray write permissions

The SDK's plugins list takes plugin factories, not plugin instances: it calls each factory's create_plugin once per invocation and the plugin it returns serves that one invocation. Import create_otel_plugin_factory to choose a view:

from aws_durable_execution_sdk_python_otel import create_otel_plugin_factory

execution = create_otel_plugin_factory()  # Default: operations parented to Workflow
invocation = create_otel_plugin_factory(mode="invocation")  # Operations parented to Invocation

Register one of these factories in plugins. Explicit mode="execution" also selects the execution view. Pass existing configuration with create_otel_plugin_factory(config, mode="invocation"). Unsupported modes raise ValueError when the factory is selected.

The steps above use mode="invocation", which is the view this guide's trace examples and screenshots show. create_otel_plugin_factory() with no mode selects the execution view instead, which parents operations to Workflow — a different span tree, not a different amount of instrumentation. See Trace Structure for both shapes.

ExecutionOtelPluginFactory and InvocationOtelPluginFactory remain supported with unchanged configuration and behavior.

Alternatively, install this package in the function artifact or a Lambda layer and select either OTel plugin by entry-point name:

DURABLE_EXECUTION_PLUGINS=otel
DURABLE_EXECUTION_PLUGINS=otel-invocation
DURABLE_EXECUTION_PLUGINS=otel-execution

otel-invocation names a default-configured InvocationOtelPluginFactory; otel and otel-execution name the same default-configured ExecutionOtelPluginFactory. The SDK discovers the selected package entry point at cold start and calls its create_plugin once per invocation, so the handler does not need to import or explicitly register the plugin. This still requires the plugin package and a configured OpenTelemetry provider and exporter, usually supplied by the ADOT layer. Installing or importing the package alone does not enable instrumentation.

Set exactly one OTel entry name. Listing both otel and otel-execution loads one factory and logs a warning because they resolve to the same object. Listing otel with otel-invocation selects different views and raises PluginLoadError.

OTel 2.0 requires core SDK 3.x and the per-invocation factory contract. Publish the coordinated core release before the plugin. Core 2.x plugin instances and OTel 1.x entry points are rejected by core 3 at handler initialization.

Configure OTel through either plugins=[...] or DURABLE_EXECUTION_PLUGINS. Registering multiple OTel factory objects raises PluginLoadError at cold start, even when they select the same view. For example, plugins=[create_otel_plugin_factory()] with DURABLE_EXECUTION_PLUGINS=otel fails because the function constructs a new factory while the entry point loads the default singleton. With custom configuration, register the factory explicitly and leave OTel entry names out of DURABLE_EXECUTION_PLUGINS. Unrelated plugins may use either source.

If both sources must register the same default view, import EXECUTION_OTEL_PLUGIN_FACTORY from aws_durable_execution_sdk_python_otel and use plugins=[EXECUTION_OTEL_PLUGIN_FACTORY] with otel or otel-execution. The loader recognizes the same factory object and skips the duplicate. INVOCATION_OTEL_PLUGIN_FACTORY works the same way with otel-invocation.

Factory classes can opt into registration metadata with __durable_registration_api__ = 1. Each opted-in class in the MRO contributes its exclusive_group; inherited groups remain in force when a subclass adds another group. The closest explicit unsupported marker disables the contract. Unmarked legacy fields and callbacks are ignored. An optional on_registration_result callback receives acceptance or rejection without constructing invocation plugins.

1. ADOT Lambda Layer

This plugin requires the AWS Distro for OpenTelemetry (ADOT) Lambda layer to export traces from your Lambda function.

The layer ARN follows the format:

arn:aws:lambda:<region>:<awsAccountId>:layer:aws-otel-python-<arch>-ver-<version>

Refer to the ADOT Lambda Layer ARNs page for the latest version number, architecture, and supported regions.

AWS CLI:

aws lambda update-function-configuration \
  --function-name your-function-name \
  --layers "arn:aws:lambda:<region>:<awsAccountId>:layer:aws-otel-python-amd64-ver-<version>"

You must also set the AWS_LAMBDA_EXEC_WRAPPER environment variable:

aws lambda update-function-configuration \
  --function-name your-function-name \
  --environment "Variables={AWS_LAMBDA_EXEC_WRAPPER=/opt/otel-instrument}"

Note: Replace <region> with your function's region and <version>/<arch> with the latest layer version and architecture from the ADOT docs.

CloudFormation / SAM:

MyFunction:
  Type: AWS::Serverless::Function
  Properties:
    Layers:
      - !Sub arn:aws:lambda:${AWS::Region}:<awsAccountId>:layer:aws-otel-python-amd64-ver-<version>
    Environment:
      Variables:
        AWS_LAMBDA_EXEC_WRAPPER: /opt/otel-instrument

CDK:

from aws_cdk import aws_lambda as lambda_

adot_layer = lambda_.LayerVersion.from_layer_version_arn(
    self,
    "AdotLayer",
    f"arn:aws:lambda:<region>:<awsAccountId>:layer:aws-otel-python-amd64-ver-<version>",
)

fn = lambda_.Function(
    self,
    "MyFunction",
    runtime=lambda_.Runtime.PYTHON_3_12,
    handler="index.handler",
    code=lambda_.Code.from_asset("lambda"),
    layers=[adot_layer],
    environment={"AWS_LAMBDA_EXEC_WRAPPER": "/opt/otel-instrument"},
)

Tip: Pin the layer version to a specific number in production deployments to avoid unexpected behavior from automatic version changes.

2. AWS X-Ray Active Tracing

Enable active tracing on your Lambda function so the _X_AMZN_TRACE_ID environment variable is populated at invocation time. The plugin uses this header to anchor the execution trace on the propagated X-Ray Root/Parent when both are valid, and preserves Sampled=1 or Sampled=0 as the backend sampling decision.

AWS Console: Lambda → Configuration → Monitoring and operations tools → Active tracing → Enable

AWS CLI:

aws lambda update-function-configuration \
  --function-name your-function-name \
  --tracing-config Mode=Active

CloudFormation / SAM:

MyFunction:
  Type: AWS::Lambda::Function
  Properties:
    TracingConfig:
      Mode: Active

CDK:

lambda_.Function(
    self,
    "MyFunction",
    tracing=lambda_.Tracing.ACTIVE,
)

Handler context propagation

The core runs the existing Start hooks, handler, output preparation, resource cleanup and End hooks on one invocation worker. Start finishes before checkpoint processing begins. End follows registered-branch joins and checkpoint shutdown, and output serialization or checkpoint errors retain their normal classification. There is no separate handler-context plugin API.

During Start, Invocation view preserves a valid active span on the canonical execution trace; when it is absent or unrelated, it attaches the Invocation span. Execution view attaches the Workflow span, including when an incoming span is on the same trace. The Invocation span's own ambient parenting is separate from the active context supplied to handler instrumentation. Both views preserve baggage.

Start hooks run in registration order. A later successful plugin that deliberately sets or clears the active span wins; OTel does not apply a second correction pass. Place OTel after a span-replacing plugin when OTel's view-specific context is desired. Baggage-only plugins that extend the current context can appear on either side. The SDK also copies the coordinator's current bindings for each map or parallel branch admission/resume when plugins are registered. Baggage and other successful bindings reach these SDK-managed callbacks, while a branch's changes cannot leak into siblings, the coordinator or a reused worker. End hooks also retain registration order and reset tokens in their owning Context; they do not promise a reverse-stack observation of other plugins' spans. The factory list is handler-scoped; each invocation owns fresh plugin instances. Checkpoint formats are unchanged.

Use the coordinated core 3.x / OTel 2.x pair for this factory API. CI tests both packages as installed wheels and verifies that legacy OTel 1.x registration is rejected clearly by core 3.

3. In your Lambda handler (index.py)

from aws_durable_execution_sdk_python import DurableContext
from aws_durable_execution_sdk_python.execution import durable_execution
from aws_durable_execution_sdk_python_otel import create_otel_plugin_factory


@durable_execution(plugins=[create_otel_plugin_factory(mode="invocation")])
def handler(event: dict, context: DurableContext) -> dict:
    result = context.step(lambda _: fetch_data(event["id"]), name="fetch-data")

    context.wait(duration=Duration.from_seconds(5))

    context.step(lambda _: process(result), name="process")

    return result

The ADOT layer supplies the global TracerProvider; the plugin handles deterministic ID generation and span lifecycle.

Drop mode="invocation" to parent operations to Workflow instead of to the current Invocation; see Trace Structure.

4. Grant Permissions

The function's execution role needs the AWSXRayDaemonWriteAccess managed policy (or equivalent permissions) if using X-Ray as the tracing backend.

Environment Variables for ADOT layer

See the ADOT sampling configuration for more details. When the backend header contains an explicit Sampled value, that backend decision takes precedence over local sampler configuration for durable spans.

Configuration

Plugin Options

from aws_durable_execution_sdk_python_otel import (
    InvocationOtelPluginFactory,
    OtelPluginConfig,
    xray_context_extractor,
)

plugin_factory = InvocationOtelPluginFactory(
    OtelPluginConfig(
        # Use a custom context extractor (default: xray_context_extractor).
        context_extractor=xray_context_extractor,
        # Custom instrumentation scope name
        # (default: "aws-durable-execution-sdk-python").
        instrument_name="my-service",
        # Install a root-logger filter that stamps trace context onto every
        # log record (default: True).
        enrich_logger=True,
    )
)

The config is resolved once and shared by every plugin the factory builds, so configuration is per handler while plugin state is per invocation.

Context Extractors

Context extractors return an ExtractedContext object, or None when no durable execution trace context is available. The object carries:

• trace_id: 128-bit OpenTelemetry trace ID
• parent_span_id: 64-bit OpenTelemetry parent span ID
• sampling: Sampling.SAMPLED, Sampling.NOT_SAMPLED, or Sampling.UNDECIDED

The plugin supports multiple strategies for extracting durable execution trace context:

from aws_durable_execution_sdk_python_otel import (
    InvocationOtelPluginFactory,
    OtelPluginConfig,
    w3c_client_context_extractor,
    xray_context_extractor,
)

# Default: X-Ray trace header (recommended for most Lambda deployments).
InvocationOtelPluginFactory(OtelPluginConfig(context_extractor=xray_context_extractor))

# W3C Trace Context via clientContext (placeholder for backend propagation support).
InvocationOtelPluginFactory(
    OtelPluginConfig(context_extractor=w3c_client_context_extractor)
)

Custom extractors should return ExtractedContext, not an OpenTelemetry Context.

Trace Structure

Both bundled plugins use the same execution ancestor:

• a propagated backend parent when _X_AMZN_TRACE_ID contains a valid Root and Parent
• otherwise a deterministic DurableExecutionRoot span derived from the durable execution ARN, with durable.execution.synthetic_root=true

InvocationOtelPlugin keeps durable operation spans under the Invocation span and links operations to Workflow:

Execution ancestor
├── Workflow
└── Invocation
    └── operation
        └── operation attempt 1

ExecutionOtelPlugin keeps operation spans under Workflow and links operations to the current Invocation span:

Execution ancestor
├── Workflow
│   └── operation
│       └── operation attempt 1
└── Invocation

If an ambient Lambda span is active and already has the execution trace ID, the Invocation span uses that ambient span as its parent. Ambient spans on a different trace are ignored for durable parenting so Invocation remains on the execution trace.

Synthetic fallback anchor

Each sampled fallback invocation creates and ends DurableExecutionRoot at invocation start and attempts to flush it through the normal invocation-end lifecycle, including when it returns PENDING or RETRY. A successfully delivered copy supplies ancestry if the execution is later stopped or times out without resuming. Export and flush failures, or termination before flushing, do not provide a delivery guarantee.

The anchor uses the existing execution-scoped span ID and the stable execution start timestamp for both its start and end. It carries no terminal outcome; Workflow remains the span for execution duration and success/failure. Retries of the first invocation and later invocations may re-export the same anchor to recover lost telemetry; export is not exactly once. Two executions sharing a propagated trace ID retain distinct ARN-scoped anchor IDs. The anchor is intentionally zero-duration, so its descendants end after it; trace viewers may flag that timing relationship even though the ancestry is valid.

The anchor uses the same configured tracer, provider resource and processors as other durable spans, but carries only the resolved sampling decision. Its SDK attributes are durable.execution.arn and durable.execution.synthetic_root; sampler-added attributes and tracestate are omitted from this repeated identity. Ordinary durable spans retain the complete resolved sampler metadata. SDK-added IDs, timestamps and anchor attributes stay stable across recovery exports; provider resources and custom processor enrichment may vary. The SDK does not replace configured service identity or freeze detector fields.

Complete remote parents are externally owned and are never materialized by the SDK. Unsampled invocations emit no anchor. Sampling remains resolved per invocation: a later sampled fallback invocation also emits the anchor even if an earlier invocation was unsampled. Missing execution start time continues to disable telemetry; no wall-clock timestamp is invented for the anchor.

Sampling

Sampling is resolved once per invocation and carried to every durable span in that invocation. Each span consumes its private sampling intent before processors run. Processor-created spans use their own configured sampling policy and normal parent-context semantics, including when a processor forwards the supplied parent context. Precedence is:

1. Sampled=1 or Sampled=0 from _X_AMZN_TRACE_ID
2. a same-trace ambient span's recording/sampled state
3. the configured OpenTelemetry sampler

The resolved decision is applied to Workflow, Invocation, operation, and attempt spans. This avoids independently querying stateful or ratio-based samplers for each durable span in the same invocation.

Status attributes

durable.invocation.status uses RETRYING when the core plugin hook reports InvocationStatus.RETRY, with OTel UNSET. The core enum remains unchanged. Operation spans use the following mapping in both views:

The original durable operation status remains in durable.operation.status. Failure status does not fabricate an exception when diagnostics are absent, including for failed step attempts. A caught operation failure leaves the enclosing Invocation and Workflow spans successful if the handler succeeds.

An exception event carries exception.type, exception.message and exception.stacktrace only when the checkpoint stored them, so a partial error such as a callback failure with a message and no type omits the field it lacks instead of reporting an invented one. An explicitly supplied empty string stays an empty string and remains distinct from an absent field. The OTel exception conventions require whichever of type and message the other lacks, so an error supplying neither records no event at all; its failure still appears in the span's error status and in durable.operation.status.

Terminal operation and attempt exception events use the same normalized end timestamp as their span, including delayed or replayed completion delivery. Execution view retains durable timing and normalizes an end at or before its start; Invocation view retains its invocation-local timestamp ordering. A checkpointless context with no durable start uses its completion time as the lower bound in Execution view. When an end timestamp is absent, the current time is chosen once for both the event and span end.

Invocation context isolation

With core 3.x, invocation hooks and the handler run on one worker in an invocation-local Context initialized from the host's bindings. Start bindings remain visible to later hooks, the handler and resource cleanup even when Start raises. The SDK retains the plugin and contains ordinary hook exceptions without rolling back context changes. Plugins own cleanup of partial bindings; End runs in the same Context as Start and can reset its tokens. The host's bindings remain unchanged after return, including after Start or End failures. This isolates the invocation's context-variable bindings from its caller; it does not undo mutations to shared objects or external side effects. The isolation applies when plugins are registered.

Log Correlation

When enrich_logger=True (the default), the plugin installs a logging filter on the root logger at invocation start. The filter stamps the trace context that is active for the emitting invocation onto log records, using these attributes:

• traceId: 32-char hex trace identifier
• spanId: 16-char hex span identifier
• otelTraceSampled: boolean indicating if the trace is sampled

Which span a record carries follows the emitting thread: the operation attempt span inside a step, the context span inside a child context, and the Invocation span for top-level handler code. A span you start yourself on the execution trace is used for records emitted inside it. A span the runtime already had active when the invocation started — the Lambda invocation span the ADOT layer creates under X-Ray active tracing — is the parent of the Invocation span rather than a substitute for it, so a top-level record still names the Invocation span. Correlation holds from the first statement of the handler, before any durable operation, and holds when several invocations run concurrently in one environment (Lambda Managed Instances): the plugin claims the invocation thread at invocation start and the SDK runs the handler body in a copy of that thread's context, so each record resolves to the invocation that emitted it rather than to whichever invocation started last. A branch of a map or parallel runs on a pool thread the invocation's context was not copied into, and the plugin claims that thread from the hooks that run on it before your branch body does.

Two cases are left unstamped, so any log formatter or schema must treat the fields as optional:

• No invocation is open — for example during environment initialization or teardown.
• The record is emitted on a thread that carries no invocation claim. A thread your code starts itself is such a thread, since Python does not copy context into a new thread, as is the SDK's background checkpointing thread. The number of invocations open in the environment does not change this: attributing an unclaimed record to the single open invocation would be wrong whenever the emitting thread belongs to a different invocation, and an uncorrelated record is preferred over one carrying another execution's trace.

Chained-invoke propagation

Both views supply the synchronous provide_propagation_metadata hook with SDK-owned types. It encodes canonical X-Ray Root, the calling operation's Parent, and resolved Sampled=1 or Sampled=0, without creating an extra span. An existing operation's actual span ID is used; before span creation, its stable ID is derived from the execution ARN and operation ID. Unrelated ambient spans cannot replace execution ownership. An operation that has already started uses its actual span's sampled flag. A deferred operation contributes metadata only while the instrumentation tracer still uses the installed DurableSampler: replacing that sampler after invocation Start may give the operation a different sampling decision, so the producer abstains instead of guessing or querying the sampler early. Inactive/mismatched executions contribute nothing. Tracer, provider and resource ownership remain unchanged.

The core now calls the collector only for a new invoke START and persists the contribution in flat ChainedInvokeOptions.XAmznTraceId. Pending and terminal replay do not recollect metadata; an uncommitted START can be retried. Separate invokes carry separate operation parents. Public invoke tests cover both views, sampled/unsampled context, parallel branches, preserved tenant/payload and replay.

For #751, deployed backend delivery and topology still require validation. The core requires boto3 1.43.114 or newer, which depends on a botocore model containing the optional field. The normal request tests use the published serializer and parameter validation. Python has no distributed-map model/START path; existing map/parallel APIs are CONTEXT operations.

OTel 2 requires core 3.x and per-invocation plugin factories. Chained-invoke propagation uses the coordinated core release and its boto3 minimum. The published model alone does not establish deployed downstream topology.

Verification

After deploying your function with the plugin configured:

1. Invoke your durable function — trigger at least one execution that includes multiple steps or a wait/resume cycle.

2. Check the CloudWatch console — Navigate to CloudWatch → Traces in the AWS Console. You should see an execution trace with:

   • A "Workflow" span exported on the terminal invocation
   • An "Invocation" span per invocation
   • Child spans for each durable operation (named after your step names)
   • All invocations of the same execution grouped under one trace ID

3. Check log correlation — verify that your logs include traceId and spanId fields matching the spans in X-Ray.

4. Confirm sampling — If you set OTEL_TRACES_SAMPLER=traceidratio and OTEL_TRACES_SAMPLER_ARG to a value less than 1.0, verify that only the expected proportion of traces appear.

5. Span links — For operations that span multiple invocations (e.g., after a wait resumes), though span links are set, they are not visualized within the CloudWatch console.

Troubleshooting

API Reference

create_otel_plugin_factory

create_otel_plugin_factory(config=None, *, mode="execution")

Constructs a new ExecutionOtelPluginFactory by default, or a new InvocationOtelPluginFactory for mode="invocation". The optional config is an existing OtelPluginConfig, passed unchanged to the selected class. For example, an application-owned provider can be supplied with create_otel_plugin_factory(OtelPluginConfig(tracer_provider=provider)).

The return value belongs in the handler's plugins list. Each invocation gets its own plugin instance. Selecting a factory does not resolve a provider or construct an invocation plugin. Mode is selected once; invalid values, including None, raise ValueError.

Register only one returned factory; see the registration guidance when using DURABLE_EXECUTION_PLUGINS. A mode read from configuration at runtime is accepted and type-checks as the union of both return types.

InvocationOtelPluginFactory

Factory for the invocation-rooted plugin, and what belongs in the SDK's plugins list. Satisfies DurableInstrumentationPluginFactory from aws_durable_execution_sdk_python: its create_plugin(info) takes an InvocationStartInfo and returns the InvocationOtelPlugin for that invocation.

InvocationOtelPluginFactory(
    OtelPluginConfig(
        tracer_provider=None,
        context_extractor=None,
        instrument_name="aws-durable-execution-sdk-python",
        enrich_logger=True,
        workflow_span_name="Workflow",
    )
)

Pass tracer_provider=... when the application owns the OpenTelemetry SDK provider. When omitted, the globally configured provider is used, resolved per invocation so a provider installed after the handler module is imported is still picked up.

INVOCATION_OTEL_PLUGIN_FACTORY is the default-configured instance the otel-invocation entry point names.

ExecutionOtelPluginFactory

Factory for the execution-rooted plugin, with the same construction and config as InvocationOtelPluginFactory. EXECUTION_OTEL_PLUGIN_FACTORY is the default-configured instance both the otel and otel-execution entry points name.

InvocationOtelPlugin

Invocation-rooted view. Implements DurableInstrumentationPlugin from aws_durable_execution_sdk_python. One instance serves exactly one invocation: the SDK builds it from the factory before the first hook fires and drops it when the invocation ends, so it holds its span registry and context tokens in ordinary instance state. Construct it directly only when driving the hooks yourself; in a handler, register the factory instead.

ExecutionOtelPlugin

Execution-rooted view. Uses the same execution ancestor and sampling behavior as InvocationOtelPlugin, but parents operation spans under Workflow and links them to Invocation. Also one instance per invocation; the identities that must agree across invocations (the trace ID, the Workflow span ID, and each operation's span ID) are derived deterministically from the execution ARN rather than carried in memory.

DeterministicIdGenerator

A custom OpenTelemetry IdGenerator that produces reproducible trace and span IDs from execution metadata. Exported for advanced use cases.

use_ids retains its existing scope-wide trace override by default. The synthetic-root implementation uses a separate internal one-span override, preventing processor-created roots from inheriting that internal ID. Existing use_ids signatures and default behavior remain unchanged.

xray_context_extractor

Default context extractor. Reads the _X_AMZN_TRACE_ID environment variable and returns ExtractedContext containing parsed Root, Parent, and Sampled fields when present.

w3c_client_context_extractor

Alternative context extractor placeholder. Returns None until backend W3C traceparent propagation is supported.

ContextExtractor

Type alias for custom context extractor functions: Callable[[InvocationStartInfo], ExtractedContext | None].

ExtractedContext / Sampling

Structured trace context and sampling decision returned by context extractors.

OtelContextLogFilter / install_log_filter

The logging filter (and its installer) used to stamp trace context onto log records. Installed automatically when enrich_logger=True; exported for manual setups, where install_log_filter(target_logger) attaches it to a logger of your choice. The filter carries no invocation identity of its own: it resolves the invocation a record belongs to at emit time, so one filter serves every invocation the environment runs, including concurrent ones.
