Summary

The TetraScience Python Connectors SDK provides utilities and APIs for building TetraScience pluggable connectors in Python. Connectors are containerized applications used for transferring data between the Tetra Data Platform (TDP) and other systems. Some examples of existing connectors:

• The S3 connector receives file events from an S3 bucket via an SQS queue and pulls the corresponding objects into TDP
• The Kepware KEPServerEX connector pulls tags from KEPServerEX over MQTT and writes corresponding JSON files to TDP
• The LabX connector can connect to multiple LabX instances and retrieve completed tasks. The LabX connector was written using this Python SDK

Usage

Connector Class

The Connector class is the core component of the SDK. It provides methods and hooks to manage the lifecycle of a connector, handle commands, perform periodic tasks, and interact with TDP.

Creating and running a connector

To create a Connector instance, you need to provide a TdpApi instance and optional ConnectorOptions. The TdpApi instance is the class that interacts with TDP

from ts_sdk_connectors_python.connector import Connector, ConnectorOptions
from ts_sdk_connectors_python.tdp_api import TdpApi

tdp_api = TdpApi()
connector = Connector(tdp_api=tdp_api, options=ConnectorOptions())

Starting the connector and running

async def main():
    tdp_api = TdpApi()
    connector = Connector(tdp_api=tdp_api, options=ConnectorOptions())
    await connector.start()
    while True:
        await asyncio.sleep(1)

asyncio.run(main())

Configuring TdpApi

Required configuration values for TdpApi can be provided either as instance args or pulled from environment variables. If any arguments are not provided, they are pulled from the environment variables.

# manually provide configuration values
tdp_api = TdpApi(
    aws_region="us-east-1",
    org_slug="tetrascience-yourorg",
    hub_id="your-hub-id",
    connector_id="your-connector-id",
    datalake_bucket="your-datalake-bucket",
    stream_bucket="your-stream-bucket",
    tdp_certificate_key="your-tdp-certificate-key",
    jwt_token_parameter="your-jwt-token-parameter",
    tdp_endpoint="https://api.tetrascience.com",
    outbound_command_queue="your-outbound-command-queue",
    kms_key_id="your-kms-key-id",
    artifact_type="connector",
    connector_token="your-connector-token",
    local_certificate_pem_location="path/to/your/certificate.pem"
)

# Automatically pull all args from environment variables
tdp_api = TdpApi()

# Some arguments provided and remaining args pulls from environment variables
tdp_api = TdpApi(datalake_bucket="your-datalake-bucket")

The following environment variables are used by the TdpApiConfig class to configure the TetraScience Data Platform API client. Note that not all of them are necessarily relevant:

Variable Name	Description
AWS_REGION	The AWS region to use.
ORG_SLUG	The organization slug for the TetraScience Data Platform.
HUB_ID	The hub ID for the connector.
CONNECTOR_ID	The unique identifier for the connector.
DATALAKE_BUCKET	The name of the datalake bucket.
STREAM_BUCKET	The name of the stream bucket.
TDP_CERTIFICATE_KEY	The key for the TDP certificate.
JWT_TOKEN_PARAMETER	Name of the SSM parameter that contains the JWT token. Used Used by non-standalone connectors
TDP_ENDPOINT	The base URL for the TetraScience Data Platform API.
OUTBOUND_COMMAND_QUEUE	The queue name for outbound commands.
KMS_KEY_ID	The KMS key ID.
ARTIFACT_TYPE	The type of artifact (e.g., connector, data-app).
CONNECTOR_TOKEN	The JWT authentication token for the connector. Used for standalone connectors to request initial AWS credentials
LOCAL_CERTIFICATE_PEM_LOCATION	The local certificate PEM file location.

Proxy support

In addition to the above environment variables, the connector uses proxy settings determined from the environment variables HTTP_PROXY, HTTPS_PROXY, and NO_PROXY. For connectors on a Hub, the connector sets these environment variables based on the Hub's proxy settings. For standalone connectors, the standalone installer will set lowercase versions of these variables. The connector checks the environment, and in the case where lowercase versions exist but uppercase ones don't, it copies the lowercase values over to uppercase.

Initialization of TdpApi

TdpApi must initialize the AWS and HTTP clients before it can communicate with the connector's AWS services and connector endpoints in TDP.

tdp_api = TdpApi()
await tdp_api.init_client(proxy_url = "127.0.0.1:3128")  # your proxy URL here, if needed
files = tdp_api.get_connector_files(...)
...

Connector example

Here is an example of a custom connector that prints "Hello World" on a scheduled interval:

from typing import Optional
from ts_sdk_connectors_python.connector import Connector, ConnectorOptions
from ts_sdk_connectors_python.custom_commands import register_command
from ts_sdk_connectors_python.tdp_api import TdpApi
from ts_sdk_connectors_python.utils import Poll

class BasicScheduledConnector(Connector):
    """Prints hello world on a scheduled interval"""

    def __init__(
        self,
        tdp_api: TdpApi,
        schedule_interval: int,
        options: Optional[ConnectorOptions] = None,
    ):
        super().__init__(tdp_api=tdp_api, options=options)
        self.poll: Optional[Poll] = None
        self.schedule_interval = schedule_interval

    async def on_start(self):
        await super().on_start()
        self._start_polling()

    async def on_stop(self):
        await super().on_stop()
        self._stop_polling()

    @register_command("TetraScience.Connector.PollingExample.SetScheduleInterval")
    async def set_schedule_interval(self, schedule_interval: str):
        self.schedule_interval = float(schedule_interval)
        self._stop_polling()
        self._start_polling()

    def _start_polling(self):
        if not self.poll:
            self.poll = Poll(self.execute_on_schedule, self.schedule_interval)
            self.poll.start()

    def _stop_polling(self):
        if self.poll:
            self.poll.stop()
            self.poll = None

    async def execute_on_schedule(self):
        print("HELLO WORLD")


# Usage
import asyncio

async def main():
    tdp_api = TdpApi()
    await api.init_client()
    connector = BasicScheduledConnector(tdp_api=tdp_api, schedule_interval=5)
    await connector.start()
    await asyncio.sleep(10)
    await connector.shutdown()

asyncio.run(main())

This example demonstrates how to create a custom connector that prints "Hello World" every 5 seconds and allows the schedule interval to be updated via a custom command. For more information on registering commands, see below.

SQL Connector

The SDK provides a SqlConnector abstract base class that simplifies building SQL-based connectors using an inheritance pattern. This allows you to easily connect to any SQL database (PostgreSQL, MySQL, SQL Server, Oracle, etc.) and incrementally retrieve data using watermarks.

For detailed documentation on the SQL Connector, including:

• Quick Start guide
• Configuration parameters and timeout configuration
• Watermark strategies with examples
• Best practices (read-only grants, query performance, indexes)
• Error codes for manifest.json
• Troubleshooting

See the SQL Connector Documentation.

For technical design details (synchronous SQLAlchemy rationale, connection pooling, runtime configuration updates), see SQL Connector Design.

Commands

TDP communicates with connectors via the command service. The data acquisition service in TDP uses a set of commands we refer to as "lifecycle commands". The Connector class implements a command listener and has several methods that are invoked when lifecycle commands come in.

Lifecycle methods and hooks

Starting and Initializing methods

• start: Starts the connector and its main activities.
  • Triggers:
    • None. Almost all connectors will call this from main.py, the default entrypoint of the container
  • Default implementation:
    • calls on_initializing hook
    • loads connector details (does not call on_connector_updated)
    • starts metrics collection, heartbeat, and command listener tasks
    • if the connector's operating status is RUNNING, calls on_start hook
    • calls on_initialized hook
• on_initializing: A developer-defined hook that is called at the beginning of the default implementation of Connector.start
  • Triggers:
    • None. In default implementation, called once by Connector.start
  • Default implementation:
    • None
• on_initialized: A developer-defined hook that is called at the end of the default implementation of Connector.start
  • Triggers:
    • None. In default implementation, called once by Connector.start
  • Default implementation:
    • None
• on_start: A developer-defined hook that runs when the connector's operating status is set to RUNNING
  • Triggers (any of the following):
    • A command with action TetraScience.Connector.Start is received
      • this corresponds to setting the connector operating status toRUNNING
    • During Connector.start if the connector's operating status is RUNNING
      • this typically happens when a disabled connector is "enabled as RUNNING"
  • Default implementation:
    • reloads connector config, which subsequently calls on_connector_updated

Running methods

• on_connector_updated: A developer-defined hook that gets called when the connector details are updated. Because this corresponds to config changes and is also triggered indirectly by on_start, it is the most common place to initialize resources for the connector to work with third-party systems. Since it is also triggered by on_stop, checking that the connector's operating status is RUNNING before starting any data ingestion is important
  • Triggers (any of the following):
    • A command with action TetraScience.Connector.UpdateConfig is received.
      • sent by the data acquisition service after valid configuration is applied
    • A command with action TetraScience.Connector.Start is received.
      • invoked by base implementation of Connector.on_start
    • A command with action TetraScience.Connector.Stop is received.
      • invoked by base implementation of Connector.on_stop
  • Default Implementation:
    • None
• validate_config: A developer defined method that determines if a given connector config is valid:
  • Triggers:
    • A command with action TetraScience.Connector.ValidateConfig is received
      • sent by the platform when a user attempts to save connector config
  • Default implementation:
    • always returns {"valid": true}

Idle and Disable/Shutdown methods

• shutdown: A method called when the connector and its container will be stopped
  • Triggers:
    • A command with action TetraScience.Connector.Shutdown is received.
      • sent by the platform when a user disables the connector
  • Default implementation:
    • calls on_shutdown
    • stops metrics collection, heartbeat, and command listener tasks
• on_shutdown: A developer-defined hook that runs when the connector is stopping. Connector specific cleanup can usually be implemented here without overriding shutdown
  • Triggers:
    • A command with action TetraScience.Connector.Shutdown is received.
      • sent by the platform when a user disables the connector
  • Default Implementation:
    • None
• on_stop: A developer-defined hook that runs when the connector's operating status is set to IDLE
  • Triggers (any of the following):
    • A command with action TetraScience.Connector.Stop is received.
      • this corresponds to setting the connector operating status to IDLE
  • Default Implementation:
    • reloads connector config, which subsequently calls on_connector_updated

Additional Connector commands

The Connector class also supports some other commands. These can be sent using the commands API

Action Name	Connector Method Called	Description	Triggers	Side-Effects
TetraScience.Connector.ListCustomCommands	handle_get_available_custom_commands	This method returns a list of available custom commands registered to the connector.
TetraScience.Connector.SetLogLevel	set_log_level	This method is used to set the log level of the connector dynamically. Supported levels DEBUG, INFO, WARNING, ERROR, CRITICAL.	User sends a command to set the log level	Adjusts the verbosity of logs without restarting the connector
custom commands	specified by @register_command decorators	Custom commands registered using the @register_command decorator.

Custom commands

Custom commands are user-defined commands that can be registered by developers to extend the functionality of a connector. This can be useful for implementing capabilities that you want the connector to have, but only to use on demand. One example would be ingesting historical data from a given time window for a connector that typically only receives new data. Another example might be requests for the connector to send information to a third-party system. This gives TDP pipelines a way to call upon the connector to act on their behalf.

Connector implements a command listener that both listens to all the previously mentioned standard commands, and also checks a connector-specific registry for custom commands. Custom commands are registered using the @register_command decorator. The decorator takes a string argument that corresponds to the action of the command. The convention for action names is TetraScience.Connector.<ConnectorName>.<CustomActionName>, as in the following example:

from ts_sdk_connectors_python.custom_commands import register_command
from ts_sdk_connectors_python.connector import Connector

class MyConnector(Connector):
    @register_command("TetraScience.Connector.ExampleConnector.MyCustomAction")
    def my_custom_action(self, body: dict):
        print(f"Action called with body: {body}")
        return None

Commands contains further technical details on custom command and command registration.

The return type of the custom command method should be either None, a dictionary, or a string that can be converted into a dictionary. Specifically, you can refer to the ts_sdk_connectors_python.models.CommandResponseBody type for more details.

Polling

The SDK provides a Poll class that allows repeated execution of a target function at a specified interval. This is useful for tasks that need to be performed periodically, such as checking the status of a resource or polling an API.

For more details on how to use the Poll class, refer to the Polling Documentation.

Logging

The SDK provides a logger to facilitate structured logging. This logger supports multi-threading, asynchronous operations, logger inheritance, and upload to CloudWatch.

Log messages are in JSON format for uptake into CloudWatch. The following are examples of log messages.

{"level":"debug","message":"Loading TDP certificates from local volume /etc/tetra/tdp-cert-chain.pem","extra":{"context":"ts_sdk_connectors_python.AuthenticatedClientCreator"}}
{"level":"info","message":"TDP certificates loaded from local volume /etc/tetra/tdp-cert-chain.pem","extra":{"context":"ts_sdk_connectors_python.AuthenticatedClientCreator"}}
{"level":"info","message":"Client initialized","extra":{"context":"ts_sdk_connectors_python.tdp_api_base","orgSlug":"tetrascience-yourorg","connectorId":"3eca48c9-3eb2-4414-a491-a8dda151da50"}}
{"level":"info","message":"Starting metrics task: cpu_usage_metrics_provider","extra":{"context":"ts_sdk_connectors_python.metrics"}}
{"level":"info","message":"Starting metrics task: memory_used_metrics_provider","extra":{"context":"ts_sdk_connectors_python.metrics"}}

Logger usage

The CloudWatch logger supports logger inheritance, allowing you to create child loggers that inherit the configuration and context of their parent loggers. This is useful for organizing log messages by component or module.

The get_logger method will return a logger that inherits from the connector SDK's root logger. Simply give the logger a useful name and begin using the logger. A new logger name will created by adding new suffix (see below). Providing the extra argument will add additional information present in all log messages with the logger. The extra argument can also be provided to any of the log methods (info, debug, warning, error, critical).

Example usage:

from ts_sdk_connectors_python.logger import get_logger
# Create a parent logger
parent_logger = get_logger("parent_logger", extra={"foo": "bar"})

assert parent_logger.name == 'ts_sdk_connectors_python.parent_logger'

parent_logger.info('my message', extra={'baz': 'bazoo'})

# expected log message
# note that 'foo' and 'baz' are included as 'extra'
# note that the logger name is also given in the 'extra.context'
{"level":"info","message":"my message","extra":{"context":"ts_sdk_connectors_python.parent_logger","foo":"bar","baz":"bazoo"}}

The following methods are provided to create logs at various levels:

logger.debug('Use this for detailed debug information. This is the lowest level and by default not
 emitted by the logger')
logger.info('Use this for general info. This is the default level for connectors')
logger.warning('Use this for warnings')
logger.error('Use this for errors. Note the exc_info which can provide stack trace info', exc_info=True)
logger.critical('Use this for critical errors that cause failure')

You may also create child loggers by using the get_child method, which will just add another suffix to an existing logger and merge provided extra.

# Create a child logger that inherits from the parent logger
child_logger = parent_logger.get_child("child", extra={"baz": "qux"})
assert child_logger.name == 'ts_sdk_connectors_python.parent_logger.child_logger'

# Log messages using the child logger
child_logger.info("This is a message from the child logger")

# note the extra is merged with the parent extra
{"level":"info","message":"my message","extra":{"context":"ts_sdk_connectors_python.parent_logger.child_logger","foo":"bar","baz":"qux"}}

Setting log levels

To reduce the volume of logs, you can set the log level. The supported levels are NOTSET, DEBUG, INFO, WARNING, ERROR, CRITICAL. This can be done via the set_root_connector_sdk_log_level method:

from ts_sdk_connectors_python.logger import set_root_connector_sdk_log_level

set_root_connector_sdk_log_level("DEBUG")

By default, all loggers made by get_logger will have an NOTSET log level, meaning they all inherit their effective log level from the root connector SDK. It is therefore not recommended to set the log level for any child loggers. Instead, use the set_root_connector_sdk_log_level method.

Connector also implements the command TetraScience.Connector.SetLogLevel which allows you to set the log level of the connector dynamically. Here is an example command request:

{
  "payload": {
    "level": "DEBUG"
  },
  "action": "TetraScience.Connector.SetLogLevel",
  "targetId": "your-connector-id"
}

CloudWatch logging and standalone connector support

If the connector is in standalone mode (meaning CONNECTOR_TOKEN env var is set), logs will get uploaded to AWS CloudWatch in addition to getting logged to console. Logging and CloudWatch reporting occurs on a separate processing thread apart from the main connector processing thread. Uploading to CloudWatch occurs in batches and whenever a batch size is hit or on a set interval. Relevant envvars related to these settings can be found in constants.py.

The CloudWatchReporter class is responsible for managing the buffering and flushing of log events to AWS CloudWatch. It handles the following tasks:

• Buffering log events.
• Flushing buffered log events to CloudWatch based on certain conditions (e.g., buffer size limit, flush interval).
• Managing the CloudWatch log stream and log group.
• Handling errors during the flushing process.

Flushing log events to AWS CloudWatch occurs for a number of reasons:

• The buffer reaches its size limit.
• The flush interval is reached.
• The flush limit is reached.
• The connector is started.
• The connector is stopped.
• An explicit flush is triggered.

OpenAPI code generation

This project uses code generation to build client libraries for interacting with the data acquisition service in TDP based on the OpenAPI specification of the service. The generated code is placed in the ts_sdk_connectors_python/openapi_codegen directory.

Typical users of the SDK will not need to generate this code. For Tetra developers, details are available here

Using the generated API client

The generated API client is used within the TdpApi class to interact with the TDP REST API. The TdpApi class provides asynchronous methods, while the TdpApiSync class provides synchronous methods.

Example usage

from ts_sdk_connectors_python.tdp_api import TdpApi
from ts_sdk_connectors_python.openapi_codegen.connectors_api_client.models import SaveConnectorValueRequest

async def main():
    api = TdpApi()
    await api.init_client()

    connector_id = "your_connector_id"
    raw_data = [
        SaveConnectorValueRequest(
            key="a-string",
            value={"some_json_field": "some_secret_value"},
            secure=True
        )
    ]

    response = await api.save_connector_data(connector_id, raw_data)
    print(response)

# Run the main function in an async event loop
import asyncio
asyncio.run(main())

For synchronous usage, use the TdpApiSync class:

from ts_sdk_connectors_python.tdp_api_sync import TdpApiSync
from ts_sdk_connectors_python.openapi_codegen.connectors_api_client.models import SaveConnectorValueRequest

def main():
    api = TdpApiSync()
    api.init_client()

    connector_id = "your_connector_id"
    raw_data = [
        SaveConnectorValueRequest(
            key="a-string",
            value={"some_json_field": "some_secret_value"},
            secure=True
        )
    ]

    response = api.save_connector_data(connector_id, raw_data)
    print(response)

    # retrieve parsed DTO object, if available
    print(response.parsed)

# Run the main function
main()

Retrieving connector data with filtering

The Python SDK supports server-side filtering when retrieving connector data. This allows you to efficiently retrieve only the data you need by specifying keys at the API level.

Using TdpApi (async)

from ts_sdk_connectors_python.tdp_api import TdpApi

async def main():
    api = TdpApi()
    await api.init_client()

    connector_id = "your_connector_id"

    # Get all connector data (no filtering)
    all_data = await api.get_connector_data(connector_id)
    print(f"All data: {len(all_data.parsed.values)} items")

    # Get specific keys only (server-side filtering)
    filtered_data = await api.get_connector_data(
        connector_id,
        keys="key1,key2,key3"  # Comma-separated list of keys
    )
    print(f"Filtered data: {len(filtered_data.parsed.values)} items")

asyncio.run(main())

Using TdpApiSync (synchronous)

from ts_sdk_connectors_python.tdp_api_sync import TdpApiSync

def main():
    api = TdpApiSync()
    api.init_client()

    connector_id = "your_connector_id"

    # Get specific keys only (server-side filtering)
    filtered_data = api.get_connector_data(
        connector_id,
        keys="key1,key2"
    )
    print(f"Filtered data: {len(filtered_data.parsed.values)} items")

main()

Using Connector class methods

The Connector class provides convenient methods that automatically use server-side filtering:

from ts_sdk_connectors_python.connector import Connector
from ts_sdk_connectors_python.tdp_api import TdpApi

async def main():
    api = TdpApi()
    await api.init_client()

    connector = Connector(api)

    # Get specific values (uses server-side filtering automatically)
    values = await connector.get_values(["key1", "key2"])
    print(f"Retrieved {len(values)} values")

    # Get single value
    single_value = await connector.get_value("key1")
    if single_value:
        print(f"Value for key1: {single_value.value}")

    # Direct access to connector data with filtering
    data = await connector.get_values(
        keys=["key1", "key2"],
    )
    print(f"Direct access: {len(data)} items")

asyncio.run(main())

Refer to the TdpApi and TdpApiSync class methods for more details on available API interactions.

Local testing with standalone connectors

For local development and testing, you can use standalone connectors to test your connector implementation against TDP resources while running your code locally. This approach allows you to:

• Test your connector logic without deploying to a Hub
• Debug and iterate quickly during development
• Validate your connector against real TDP services

Prerequisites

1. Build your local Docker image: Ensure you have built a local Docker image of your connector
2. Access to TDP environment: You need access to a TDP organization and appropriate permissions
3. Standalone installer: Access to the TetraScience standalone connector installer

Setup process

Step 1: build your local connector image

First, build your connector as a Docker image locally. This typically involves:

# Example build command (adjust based on your connector's Dockerfile)
docker build -t my-connector:local .

Step 2: use the standalone installer

1. Run the standalone connector installer provided by TetraScience

2. When prompted for the connector image during installation, provide your local image name instead of an official image:

   # Instead of using an official image like:
   # tetrascience/my-connector:v1.0.0
   
   # Use your local build:
   my-connector:local
   

3. The installer will:

   • Set up the necessary TDP resources (tokens, certificates, etc.)
   • Configure environment variables for standalone operation
   • Create the appropriate Docker run configuration pointing to your local image

Step 3: environment configuration

The standalone installer will configure the following key environment variables:

• CONNECTOR_TOKEN: Authentication token for standalone deployment
• TDP_ENDPOINT: TDP API endpoint
• ORG_SLUG: Your organization identifier
• CONNECTOR_ID: The connector instance ID
• Other TDP-specific configuration as needed

Step 4: running your local connector

After setup, your connector will run using your local Docker image but connect to real TDP services for authentication, data storage, and command processing.

Alternative: running containerless locally

It is also possible for testing to run the connector locally without Docker:

• Skip Step 1 above
• Get the connector token and standalone installer in Step 2, but do not run it
• From the installer.sh file, you can extract values for the environment variables (other than CONNECTOR_TOKEN, which you can get as part of Step 2) and export them. The necessary environment variables are those mentioned in Configuring TdpApi
• In Step 4, run the entrypoint of the connector directly

Important notes

• Ensure your local Docker image is built before running the standalone installer
• The standalone installer handles all TDP resource provisioning and configuration
• Your local connector will have the same capabilities as a Hub-deployed connector
• Use this method for development and testing; production deployments should use Hub or standalone deployment of the official image

Running tests

Unit tests and integration tests are located in the __tests__/unit and __tests__/integration directories, respectively. To run unit tests, execute:

poetry run pytest

To run integration tests against the TDP API, export the connector environment variables for tests and run:

poetry run pytest --integration

It is easiest to run the integration tests by following the procedure described in Local testing with standalone connectors.
