Azure Tables SDK for Python

\n

NoSQL key-value store for structured data (Azure Storage Tables or Cosmos DB Table API).

\n

Installation

\n
pip install azure-data-tables azure-identity\n
\n

Environment Variables

\n
# Azure Storage Tables\nAZURE_STORAGE_ACCOUNT_URL=https://<account>.table.core.windows.net  # Required for Azure Storage Tables\n\n# Cosmos DB Table API\nCOSMOS_TABLE_ENDPOINT=https://<account>.table.cosmos.azure.com  # Required for Cosmos DB Table API\nAZURE_TOKEN_CREDENTIALS=prod # Required only if DefaultAzureCredential is used in production\n
\n

Authentication & Lifecycle

\n
\n

\uD83D\uDD11 Two rules apply to every code sample below:

\n
    \n
  1. Prefer DefaultAzureCredential. It works locally (Azure CLI / VS Code / Developer CLI) and in Azure (managed identity, workload identity) with no code change. Avoid connection strings, account/API keys — they bypass Entra audit and rotation.\n
      \n
    • Local dev: DefaultAzureCredential works as-is.
      • \n
    • Production: set AZURE_TOKEN_CREDENTIALS=prod (or AZURE_TOKEN_CREDENTIALS=<specific_credential>) to constrain the credential chain to production-safe credentials.
      • \n
    \n
    2. \n
  2. Wrap every client in a context manager so HTTP transports, sockets, and token caches are released deterministically:\n
      \n
    • Sync: with <Client>(...) as client:
      • \n
    • Async: async with <Client>(...) as client: and async with DefaultAzureCredential() as credential: (from azure.identity.aio)
      • \n
    \n
    3. \n
\n

Snippets may abbreviate this setup, but production code should always follow both rules.

\n
\n
import os\nfrom azure.identity import DefaultAzureCredential, ManagedIdentityCredential\nfrom azure.data.tables import TableServiceClient, TableClient\n\n# Local dev: DefaultAzureCredential. Production: set AZURE_TOKEN_CREDENTIALS=prod or AZURE_TOKEN_CREDENTIALS=<specific_credential>\ncredential = DefaultAzureCredential(require_envvar=True)\n# Or use a specific credential directly in production:\n# See https://learn.microsoft.com/python/api/overview/azure/identity-readme?view=azure-python#credential-classes\n# credential = ManagedIdentityCredential()\n\nendpoint = \"https://<account>.table.core.windows.net\"\n\n# Service client (manage tables)\nwith TableServiceClient(endpoint=endpoint, credential=credential) as service_client:\n    # Use service_client here (see following sections for operations)\n    ...\n\n# Table client (work with entities)\nwith TableClient(endpoint=endpoint, table_name=\"mytable\", credential=credential) as table_client:\n    # Use table_client here (see following sections for operations)\n    ...\n
\n

\n

Table Operations

\n
# Create table\nservice_client.create_table(\"mytable\")\n\n# Create if not exists\nservice_client.create_table_if_not_exists(\"mytable\")\n\n# Delete table\nservice_client.delete_table(\"mytable\")\n\n# List tables\nfor table in service_client.list_tables():\n    print(table.name)\n\n# Get table client\ntable_client = service_client.get_table_client(\"mytable\")\n
\n

Entity Operations

\n

Important: Every entity requires PartitionKey and RowKey (together form unique ID).

\n

Create Entity

\n
entity = {\n    \"PartitionKey\": \"sales\",\n    \"RowKey\": \"order-001\",\n    \"product\": \"Widget\",\n    \"quantity\": 5,\n    \"price\": 9.99,\n    \"shipped\": False\n}\n\n# Create (fails if exists)\ntable_client.create_entity(entity=entity)\n\n# Upsert (create or replace)\ntable_client.upsert_entity(entity=entity)\n
\n

Get Entity

\n
# Get by key (fastest)\nentity = table_client.get_entity(\n    partition_key=\"sales\",\n    row_key=\"order-001\"\n)\nprint(f\"Product: {entity['product']}\")\n
\n

Update Entity

\n
# Replace entire entity\nentity[\"quantity\"] = 10\ntable_client.update_entity(entity=entity, mode=\"replace\")\n\n# Merge (update specific fields only)\nupdate = {\n    \"PartitionKey\": \"sales\",\n    \"RowKey\": \"order-001\",\n    \"shipped\": True\n}\ntable_client.update_entity(entity=update, mode=\"merge\")\n
\n

Delete Entity

\n
table_client.delete_entity(\n    partition_key=\"sales\",\n    row_key=\"order-001\"\n)\n
\n

Query Entities

\n

Query Within Partition

\n
# Query by partition (efficient)\nentities = table_client.query_entities(\n    query_filter=\"PartitionKey eq 'sales'\"\n)\nfor entity in entities:\n    print(entity)\n
\n

Query with Filters

\n
# Filter by properties\nentities = table_client.query_entities(\n    query_filter=\"PartitionKey eq 'sales' and quantity gt 3\"\n)\n\n# With parameters (safer)\nentities = table_client.query_entities(\n    query_filter=\"PartitionKey eq @pk and price lt @max_price\",\n    parameters={\"pk\": \"sales\", \"max_price\": 50.0}\n)\n
\n

Select Specific Properties

\n
entities = table_client.query_entities(\n    query_filter=\"PartitionKey eq 'sales'\",\n    select=[\"RowKey\", \"product\", \"price\"]\n)\n
\n

List All Entities

\n
# List all (cross-partition - use sparingly)\nfor entity in table_client.list_entities():\n    print(entity)\n
\n

Batch Operations

\n
from azure.data.tables import TableTransactionError\n\n# Batch operations (same partition only!)\noperations = [\n    (\"create\", {\"PartitionKey\": \"batch\", \"RowKey\": \"1\", \"data\": \"first\"}),\n    (\"create\", {\"PartitionKey\": \"batch\", \"RowKey\": \"2\", \"data\": \"second\"}),\n    (\"upsert\", {\"PartitionKey\": \"batch\", \"RowKey\": \"3\", \"data\": \"third\"}),\n]\n\ntry:\n    table_client.submit_transaction(operations)\nexcept TableTransactionError as e:\n    print(f\"Transaction failed: {e}\")\n
\n

Async Client

\n
from azure.data.tables.aio import TableServiceClient, TableClient\nfrom azure.identity.aio import DefaultAzureCredential\n\nasync def table_operations():\n    async with DefaultAzureCredential() as credential:\n        async with TableClient(\n            endpoint=\"https://<account>.table.core.windows.net\",\n            table_name=\"mytable\",\n            credential=credential\n        ) as client:\n            # Create\n            await client.create_entity(entity={\n                \"PartitionKey\": \"async\",\n                \"RowKey\": \"1\",\n                \"data\": \"test\"\n            })\n            \n            # Query\n            async for entity in client.query_entities(\"PartitionKey eq 'async'\"):\n                print(entity)\n\nimport asyncio\nasyncio.run(table_operations())\n

Best Practices

\n
    \n
  1. Pick sync OR async and stay consistent. Do not mix azure.data.tables sync clients with azure.data.tables.aio async clients in the same call path. Choose one mode per module.
    2. \n
  2. Always use context managers for clients and async credentials. Wrap every client in with TableClient(...) as client: (sync) or async with TableClient(...) as client: (async). For async DefaultAzureCredential from azure.identity.aio, also use async with credential: so tokens and transports are cleaned up.
    3. \n
  3. Use DefaultAzureCredential for portable auth across local dev and Azure (avoid connection strings / API keys when possible).
    4. \n
  4. Design partition keys for query patterns and even distribution
    5. \n
  5. Query within partitions whenever possible (cross-partition is expensive)
    6. \n
  6. Use batch operations for multiple entities in same partition
    7. \n
  7. Use upsert_entity for idempotent writes
    8. \n
  8. Use parameterized queries to prevent injection
    9. \n
  9. Keep entities small — max 1MB per entity
    10. \n
  10. Use async client for high-throughput scenarios
    11. \n
