Designed for Python 3.11+ running in Dockerized Azure Function Apps and Web Apps.

Installation

uv add azpaddypy

Quick Start

from azpaddypy import AzureStorage, AzureIdentity, create_azure_storage

# Factory function (cached instances, auto-creates identity)
storage = create_azure_storage(
    account_url="https://myaccount.blob.core.windows.net/",
    service_name="my_service",
)

# Or explicit identity
identity = AzureIdentity(service_name="my_service")
storage = AzureStorage(
    account_url="https://myaccount.blob.core.windows.net/",
    azure_identity=identity,
    enable_file_storage=True,
)

Storage Operations

Blob Storage

# Upload
storage.upload_blob(
    container_name="documents",
    blob_name="report.pdf",
    data=pdf_bytes,
    content_type="application/pdf",
    metadata={"author": "team"},
)

# Download (returns None if not found)
data = storage.download_blob(container_name="documents", blob_name="report.pdf")

# Upload and get SAS URL
sas_url = storage.upload_blob_with_sas(
    container_name="documents",
    blob_name="report.pdf",
    data=pdf_bytes,
    sas_permission="r",
    sas_expiry_delta=timedelta(hours=3),
)

# List, exists, delete
blobs = storage.list_blobs(container_name="documents", name_starts_with="reports/")
exists = storage.blob_exists(container_name="documents", blob_name="report.pdf")
storage.delete_blob(container_name="documents", blob_name="report.pdf")

# Metadata upsert (merges with existing)
storage.upsert_blob_metadata(
    container_name="documents",
    blob_name="report.pdf",
    metadata={"status": "processed"},
)

# SAS token generation
blob_sas = storage.get_blob_sas(container_name="docs", blob_name="file.pdf")
container_sas = storage.get_container_sas(container_name="docs", permission="r")

Append Blob Storage

Append blobs are optimized for append operations such as logging, auditing, or streaming data. Each append block can be up to 4 MiB. Unlike block blobs, append blobs do not support overwriting existing content.

# Create an empty append blob
storage.create_append_blob(
    container_name="logs",
    blob_name="app-2026-04-05.log",
    content_type="text/plain; charset=utf-8",
    metadata={"source": "web-app"},
)

# Append data blocks
storage.append_block(
    container_name="logs",
    blob_name="app-2026-04-05.log",
    data="2026-04-05T10:00:00Z INFO Application started\n",
)

storage.append_block(
    container_name="logs",
    blob_name="app-2026-04-05.log",
    data=b"2026-04-05T10:00:01Z DEBUG Connection pool initialized\n",
)

# Convenience: create-if-missing + append in one call
storage.append_blob_from_text(
    container_name="logs",
    blob_name="app-2026-04-05.log",
    text="2026-04-05T10:05:00Z WARN High memory usage\n",
    create_if_not_exists=True,  # default, skips creation if blob already exists
)

File Share Storage

Requires enable_file_storage=True. Uses Azure File Shares (SMB/NFS), not blob storage.

storage = AzureStorage(
    account_url="https://myaccount.blob.core.windows.net/",
    azure_identity=identity,
    enable_file_storage=True,
)

# Upload (auto-creates parent directories)
storage.upload_share_file(
    share_name="myshare",
    file_path="reports/2026/q1.pdf",
    data=pdf_bytes,
    content_type="application/pdf",
)

# Download (returns None if not found)
data = storage.download_share_file(share_name="myshare", file_path="reports/2026/q1.pdf")

# List files and directories
items = storage.list_share_files(share_name="myshare", directory_path="reports/2026")
# Returns: [{"name": "q1.pdf", "is_directory": False, "size": 1024}, ...]

# Exists, properties, delete
exists = storage.share_file_exists(share_name="myshare", file_path="reports/2026/q1.pdf")
props = storage.get_share_file_properties(share_name="myshare", file_path="reports/2026/q1.pdf")
storage.delete_share_file(share_name="myshare", file_path="reports/2026/q1.pdf")

# Directory management
storage.create_share_directory(share_name="myshare", directory_path="reports/2026/q2")
storage.delete_share_directory(share_name="myshare", directory_path="reports/2026/q2")

# Metadata upsert (merges with existing)
storage.upsert_share_file_metadata(
    share_name="myshare",
    file_path="reports/2026/q1.pdf",
    metadata={"reviewed": "true"},
)

Queue Storage

# Send
storage.send_message(
    queue_name="tasks",
    content='{"task": "process"}',
    visibility_timeout=30,
    time_to_live=3600,
)

# Receive
messages = storage.receive_messages(queue_name="tasks", messages_per_page=5)
for msg in messages:
    print(msg["id"], msg["content"])
    storage.delete_message(
        queue_name="tasks",
        message_id=msg["id"],
        pop_receipt=msg["pop_receipt"],
    )

Builder Pattern

For complex multi-resource setups:

from azpaddypy.builder import AzureManagementBuilder, AzureResourceBuilder
from azpaddypy.builder.directors import ConfigurationSetupDirector

# One-liner setup with director
config = ConfigurationSetupDirector.default_setup(
    service_name="my_app",
    service_version="1.0.0",
)

# Or step-by-step with builders
mgmt = (
    AzureManagementBuilder()
    .with_logger(service_name="my_app")
    .with_identity()
    .with_keyvault(vault_url="https://myvault.vault.azure.net/")
    .build()
)

resources = (
    AzureResourceBuilder(mgmt, env_config)
    .with_storage("default", enable_blob=True, enable_queue=True)
    .with_storage("archive", account_url="https://archive.blob.core.windows.net/", enable_file=True)
    .build()
)

storage = resources.get_storage("default")
archive = resources.get_storage("archive")

Key Vault

from azpaddypy import AzureKeyVault, create_azure_keyvault

kv = create_azure_keyvault(
    vault_url="https://myvault.vault.azure.net/",
    service_name="my_service",
)

secret = kv.get_secret("database-connection-string")

Observability

All operations include OpenTelemetry spans and structured logging via Application Insights.

storage = AzureStorage(
    account_url="https://myaccount.blob.core.windows.net/",
    azure_identity=identity,
    connection_string="InstrumentationKey=...",  # App Insights
)

# Correlation tracking across distributed calls
storage.set_correlation_id("request-abc-123")

Feature Flags

Enable only the storage services you need:

Flag	Default	Service
enable_blob_storage	True	BlobServiceClient
enable_file_storage	False	ShareServiceClient (requires token_intent="backup" RBAC)
enable_queue_storage	True	QueueServiceClient
