+# Azure Data Tables client library for Python
+
+Azure Data Tables is a NoSQL data storing service that can be accessed from anywhere in the world via authenticated calls using HTTP or HTTPS. 
+Tables scale as needed to support the amount of data inserted, and allow for the storing of data with non-complex accessing. 
+Tables scale as needed to support the amount of data inserted, and allow for the storing of data with non-complex accessing. 
+The Azure Data Tables client can be used to access Azure Storage or Cosmos accounts.
+
+Common uses of Azure Data Tables include:
+
+* Storing structured data in the form of tables
+* Quickly querying data using a clustered index
+
+[Source code](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/table/azure-data-tables/azure/data/tables) | [Package (PyPI)](https://pypi.org/project/azure-data-tables/) | [API reference documentation](https://aka.ms/azsdk/python/table/docs) | [Product documentation](https://docs.microsoft.com/azure/storage/) | [Samples](https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/tables/azure-data-tables/samples)
+
+## Getting started
+
+### Prerequisites
+* Python 2.7, or 3.5 or later is required to use this package.
+* You must have an [Azure subscription](https://azure.microsoft.com/free/) and an
+[Azure storage account](https://docs.microsoft.com/azure/storage/common/storage-account-overview) to use this package
+ or you must have a [Azure Cosmos Account](https://docs.microsoft.com/en-us/azure/cosmos-db/account-overview).
+
+### Install the package
+Install the Azure Data Tables client library for Python with [pip](https://pypi.org/project/pip/):
+
+```bash
+pip install --pre azure-data-tables
+```
+
+### Create a storage account
+If you wish to create a new cosmos storage account, you can use the [Azure Cosmos DB](https://docs.microsoft.com/en-us/azure/cosmos-db/create-cosmosdb-resources-portal)
+If you wish to create a new storage account, you can use the
+[Azure Portal](https://docs.microsoft.com/azure/storage/common/storage-quickstart-create-account?tabs=azure-portal),
+[Azure PowerShell](https://docs.microsoft.com/azure/storage/common/storage-quickstart-create-account?tabs=azure-powershell),
+or [Azure CLI](https://docs.microsoft.com/azure/storage/common/storage-quickstart-create-account?tabs=azure-cli):
+
+```bash
+# Create a new resource group to hold the storage account -
+# if using an existing resource group, skip this step
+az group create --name MyResourceGroup --location westus2
+
+# Create the storage account
+az storage account create -n mystorageaccount -g MyResourceGroup
+```
+
+### Create the client
+The Azure Data Tables client library for Python allows you to interact with two types of resources: the
+account and tables, and entities. Interaction with these resources starts with an instance of a [client](#clients).
+To create a client object, you will need the account's table service endpoint URL and a credential that allows
+you to access the account:
+
+```python
+from azure.data.tables import TableServiceClient
+
+service = TableServiceClient(account_url="https://<myaccount>.table.core.windows.net/", credential=credential)
+```
+
+#### Looking up the account URL
+You can find the account's table service URL using the 
+[Azure Portal](https://docs.microsoft.com/azure/storage/common/storage-account-overview#storage-account-endpoints),
+[Azure PowerShell](https://docs.microsoft.com/powershell/module/az.storage/get-azstorageaccount),
+or [Azure CLI](https://docs.microsoft.com/cli/azure/storage/account?view=azure-cli-latest#az-storage-account-show):
+
+```bash
+# Get the table service URL for the account
+az storage account show -n mystorageaccount -g MyResourceGroup --query "primaryEndpoints.table"
+```
+
+#### Types of credentials
+The `credential` parameter may be provided in a number of different forms, depending on the type of
+[authorization](https://docs.microsoft.com/azure/storage/common/storage-auth) you wish to use:
+1. To use a [shared access signature (SAS) token](https://docs.microsoft.com/azure/storage/common/storage-sas-overview),
+   provide the token as a string. If your account URL includes the SAS token, omit the credential parameter.
+   You can generate a SAS token from the Azure Portal under "Shared access signature" or use one of the `generate_sas()`
+   functions to create a sas token for the account or table:
+
+```python
+    from datetime import datetime, timedelta
+    from azure.data.tables import TableServiceClient, generate_account_sas, ResourceTypes, AccountSasPermissions
+
+    sas_token = generate_account_sas(
+        account_name="<account-name>",
+        account_key="<account-access-key>",
+        resource_types=ResourceTypes(service=True),
+        permission=AccountSasPermissions(read=True),
+        expiry=datetime.utcnow() + timedelta(hours=1)
+    )
+
+    table_service_client = TableServiceClient(account_url="https://<my_account_name>.table.core.windows.net", credential=sas_token)
+```
+
+2. To use an account [shared key](https://docs.microsoft.com/rest/api/storageservices/authenticate-with-shared-key/)
+   (aka account key or access key), provide the key as a string. This can be found in the Azure Portal under the "Access Keys" 
+   section or by running the following Azure CLI command:
+
+    ```az storage account keys list -g MyResourceGroup -n mystorageaccount```
+
+    Use the key as the credential parameter to authenticate the client:
+    ```python
+    from azure.data.tables import TableServiceClient
+    service = TableServiceClient(account_url="https://<my_account_name>.table.core.windows.net", credential="<account_access_key>")
+    ```
+
+#### Creating the client from a connection string
+Depending on your use case and authorization method, you may prefer to initialize a client instance with a
+connection string instead of providing the account URL and credential separately. To do this, pass the 
+connection string to the client's `from_connection_string` class method:
+
+```python
+from azure.data.tables import TableServiceClient
+
+connection_string = "DefaultEndpointsProtocol=https;AccountName=xxxx;AccountKey=xxxx;EndpointSuffix=core.windows.net"
+service = TableServiceClient.from_connection_string(conn_str=connection_string)
+```
+
+The connection string to your account can be found in the Azure Portal under the "Access Keys" section or by running the following CLI command:
+
+```bash
+az storage account show-connection-string -g MyResourceGroup -n mystorageaccount
+```
+
+## Key concepts
+The following components make up the Azure Data Tables Service:
+* The account
+* A table within the account, which contains a set of entities
+* An entity within a table, as a dictionary
+
+The Azure Data Tables client library for Python allows you to interact with each of these components through the
+use of a dedicated client object.
+
+### Clients
+Two different clients are provided to to interact with the various components of the Table Service:
+1. [TableServiceClient](https://aka.ms/azsdk/python/table/docs) -
+    this client represents interaction with the Azure account itself, and allows you to acquire preconfigured
+    client instances to access the tables within. It provides operations to retrieve and configure the account
+    properties as well as query, create, and delete tables within the account. To perform operations on a specific table,
+    retrieve a client using the `get_table_client` method.
+2. [TableClient](https://aka.ms/azsdk/python/table/docs) -
+    this client represents interaction with a specific table (which need not exist yet). It provides operations to
+    create, delete, or update a table and includes operations to query, get, and upsert entities
+    within it.
+
+### Entities
+* **Create** - Adds an entity to the table.
+* **Delete** - Deletes an entity from the table.
+* **Update** - Updates an entities information by either merging or replacing the existing entity.
+* **Query** - Queries existing entities in a table based off of the QueryOptions (OData).
+* **Get** - Gets a specific entity from a table by partition and row key.
+* **Upsert** - Merges or replaces an entity in a table, or if the entity does not exist, inserts the entity. 
+
+## Examples
+
+The following sections provide several code snippets covering some of the most common Table tasks, including:
+
+* [Creating a table](#creating-a-table "Creating a table")
+* [Creating entities](#creating-entities "Creating entities")
+* [Querying entities](#querying-entities "Querying entities")
+
+
+### Creating a table
+Create a table in your account
+
+```python
+from azure.data.tables import TableServiceClient
+
+table_service_client = TableServiceClient.from_connection_string(conn_str="<connection_string>")
+table_service_client.create_table(table_name="myTable")
+```
+
+### Creating entities
+Create entities in the table
+
+```python
+from azure.data.tables import TableClient
+
+my_entity = {'PartitionKey':'part','RowKey':'row'}
+
+table_client = TableClient.from_connection_string(conn_str="<connection_string>", table_name="myTable")
+entity = table_client.create_entity(entity=my_entity)
+```
+
+### Querying entities
+Querying entities in the table
+
+```python
+from azure.data.tables import TableClient
+
+my_filter = "text eq Marker"
+
+table_client = TableClient.from_connection_string(conn_str="<connection_string>", table_name="mytable")
+entity = table_client.query_entities(filter=my_filter)
+```
+
+## Optional Configuration
+
+Optional keyword arguments can be passed in at the client and per-operation level. The azure-core [reference documentation](https://azuresdkdocs.blob.core.windows.net/$web/python/azure-core/latest/azure.core.html) describes available configurations for retries, logging, transport protocols, and more.
+
+
+### Retry Policy configuration
+
+Use the following keyword arguments when instantiating a client to configure the retry policy:
+
+* __retry_total__ (int): Total number of retries to allow. Takes precedence over other counts.
+Pass in `retry_total=0` if you do not want to retry on requests. Defaults to 10.
+* __retry_connect__ (int): How many connection-related errors to retry on. Defaults to 3.
+* __retry_read__ (int): How many times to retry on read errors. Defaults to 3.
+* __retry_status__ (int): How many times to retry on bad status codes. Defaults to 3.
+* __retry_to_secondary__ (bool): Whether the request should be retried to secondary, if able.
+This should only be enabled of RA-GRS accounts are used and potentially stale data can be handled.
+Defaults to `False`.
+
+### Other client / per-operation configuration
+
+Other optional configuration keyword arguments that can be specified on the client or per-operation.
+
+**Client keyword arguments:**
+
+* __connection_timeout__ (int): Optionally sets the connect and read timeout value, in seconds.
+* __transport__ (Any): User-provided transport to send the HTTP request.
+
+**Per-operation keyword arguments:**
+
+* __raw_response_hook__ (callable): The given callback uses the response returned from the service.
+* __raw_request_hook__ (callable): The given callback uses the request before being sent to service.
+* __client_request_id__ (str): Optional user specified identification of the request.
+* __user_agent__ (str): Appends the custom value to the user-agent header to be sent with the request.
+* __logging_enable__ (bool): Enables logging at the DEBUG level. Defaults to False. Can also be passed in at
+the client level to enable it for all requests.
+* __headers__ (dict): Pass in custom headers as key, value pairs. E.g. `headers={'CustomValue': value}`
+
+
+## Troubleshooting
+### General
+Azure Data Tables clients raise exceptions defined in [Azure Core](https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/core/azure-core/README.md).
+All Table service operations will throw a `HttpResponseError` on failure with helpful [error codes](https://docs.microsoft.com/en-us/rest/api/storageservices/table-service-error-codes).
+
+### Logging
+This library uses the standard
+[logging](https://docs.python.org/3/library/logging.html) library for logging.
+Basic information about HTTP sessions (URLs, headers, etc.) is logged at INFO
+level.
+
+Detailed DEBUG level logging, including request/response bodies and unredacted
+headers, can be enabled on a client with the `logging_enable` argument:
+```python
+import sys
+import logging
+from azure.data.tables import TableServiceClient
+
+# Create a logger for the 'azure.data.tables' SDK
+logger = logging.getLogger('azure.data.tables')
+logger.setLevel(logging.DEBUG)
+
+# Configure a console output
+handler = logging.StreamHandler(stream=sys.stdout)
+logger.addHandler(handler)
+
+# This client will log detailed information about its HTTP sessions, at DEBUG level
+service_client = TableServiceClient.from_connection_string("your_connection_string", logging_enable=True)
+```
+
+Similarly, `logging_enable` can enable detailed logging for a single operation,
+even when it isn't enabled for the client:
+```py
+service_client.get_service_stats(logging_enable=True)
+```
+
