TableService Class

This is the main class managing Azure Table resources.

The Azure Table service offers structured storage in the form of tables. Tables store data as collections of entities. Entities are similar to rows. An entity has a primary key and a set of properties. A property is a name, typed-value pair, similar to a column. The Table service does not enforce any schema for tables, so two entities in the same table may have different sets of properties. Developers may choose to enforce a schema on the client side. A table may contain any number of entities.

Constructor

TableService(account_name=None, account_key=None, sas_token=None, is_emulated=False, protocol='https', endpoint_suffix='core.windows.net', request_session=None, connection_string=None, socket_timeout=None)

Parameters

Name	Description
account_name	str The storage account name. This is used to authenticate requests signed with an account key and to construct the storage endpoint. It is required unless a connection string is given. default value: None
account_key	str The storage account key. This is used for shared key authentication. default value: None
sas_token	str A shared access signature token to use to authenticate requests instead of the account key. If account key and sas token are both specified, account key will be used to sign. default value: None
is_emulated	bool Whether to use the emulator. Defaults to False. If specified, will override all other parameters besides connection string and request session. default value: False
protocol	str The protocol to use for requests. Defaults to https. default value: https
endpoint_suffix	str The host base component of the url, minus the account name. Defaults to Azure (core.windows.net). Override this to use the China cloud (core.chinacloudapi.cn). default value: core.windows.net
request_session	<xref:requests.Session> The session object to use for http requests. default value: None
connection_string	str If specified, this will override all other parameters besides request session. See http://azure.microsoft.com/en-us/documentation/articles/storage-configure-connection-string/ for the connection string format. default value: None
socket_timeout	int If specified, this will override the default socket timeout. The timeout specified is in seconds. See DEFAULT_SOCKET_TIMEOUT in _constants.py for the default value. default value: None

Variables

Name	Description
key_encryption_key	object The key-encryption-key optionally provided by the user. If provided, will be used to encrypt/decrypt in supported methods. For methods requiring decryption, either the key_encryption_key OR the resolver must be provided. If both are provided, the resolver will take precedence. Must implement the following methods for APIs requiring encryption: wrap_key(key)–wraps the specified key (bytes) using an algorithm of the user's choice. Returns the encrypted key as bytes. get_key_wrap_algorithm()–returns the algorithm used to wrap the specified symmetric key. get_kid()–returns a string key id for this key-encryption-key. Must implement the following methods for APIs requiring decryption: unwrap_key(key, algorithm)–returns the unwrapped form of the specified symmetric key using the string-specified algorithm. get_kid()–returns a string key id for this key-encryption-key.
key_resolver_function	kid) (<xref:function> A function to resolve keys optionally provided by the user. If provided, will be used to decrypt in supported methods. For methods requiring decryption, either the key_encryption_key OR the resolver must be provided. If both are provided, the resolver will take precedence. It uses the kid string to return a key-encryption-key implementing the interface defined above.
encryption_resolver_functions	<xref:function>(<xref:partition_key>, <xref:row_key>, <xref:property_name>) A function that takes in an entity's partition key, row key, and property name and returns a boolean that indicates whether that property should be encrypted.
require_encryption	bool A flag that may be set to ensure that all messages successfully uploaded to the queue and all those downloaded and successfully read from the queue are/were encrypted while on the server. If this flag is set, all required parameters for encryption/decryption must be provided. See the above comments on the key_encryption_key and resolver.

Methods

batch	Creates a batch object which can be used as a context manager. Commits the batch on exit.
commit_batch	Commits a <xref:azure.storage.table.TableBatch> request.
create_table	Creates a new table in the storage account.
delete_entity	Deletes an existing entity in a table. Throws if the entity does not exist. When an entity is successfully deleted, the entity is immediately marked for deletion and is no longer accessible to clients. The entity is later removed from the Table service during garbage collection.
delete_table	Deletes the specified table and any data it contains. When a table is successfully deleted, it is immediately marked for deletion and is no longer accessible to clients. The table is later removed from the Table service during garbage collection. Note that deleting a table is likely to take at least 40 seconds to complete. If an operation is attempted against the table while it was being deleted, an <xref:azure.cosmosdb.table.tableservice.AzureConflictHttpError> will be thrown.
exists	Returns a boolean indicating whether the table exists.
extract_date_and_request_id
generate_account_shared_access_signature	Generates a shared access signature for the table service. Use the returned signature with the sas_token parameter of TableService.
generate_table_shared_access_signature	Generates a shared access signature for the table. Use the returned signature with the sas_token parameter of TableService.
get_entity	Get an entity from the specified table. Throws if the entity does not exist.
get_table_acl	Returns details about any stored access policies specified on the table that may be used with Shared Access Signatures.
get_table_service_properties	Gets the properties of a storage account's Table service, including logging, analytics and CORS rules.
get_table_service_stats	Retrieves statistics related to replication for the Table service. It is only available when read-access geo-redundant replication is enabled for the storage account. With geo-redundant replication, Azure Storage maintains your data durable in two locations. In both locations, Azure Storage constantly maintains multiple healthy replicas of your data. The location where you read, create, update, or delete data is the primary storage account location. The primary location exists in the region you choose at the time you create an account via the Azure Management Azure classic portal, for example, North Central US. The location to which your data is replicated is the secondary location. The secondary location is automatically determined based on the location of the primary; it is in a second data center that resides in the same region as the primary location. Read-only access is available from the secondary location, if read-access geo-redundant replication is enabled for your storage account.
insert_entity	Inserts a new entity into the table. Throws if an entity with the same PartitionKey and RowKey already exists. When inserting an entity into a table, you must specify values for the PartitionKey and RowKey system properties. Together, these properties form the primary key and must be unique within the table. Both the PartitionKey and RowKey values must be string values; each key value may be up to 64 KB in size. If you are using an integer value for the key value, you should convert the integer to a fixed-width string, because they are canonically sorted. For example, you should convert the value 1 to 0000001 to ensure proper sorting.
insert_or_merge_entity	Merges an existing entity or inserts a new entity if it does not exist in the table. If insert_or_merge_entity is used to merge an entity, any properties from the previous entity will be retained if the request does not define or include them.
insert_or_replace_entity	Replaces an existing entity or inserts a new entity if it does not exist in the table. Because this operation can insert or update an entity, it is also known as an "upsert" operation. If insert_or_replace_entity is used to replace an entity, any properties from the previous entity will be removed if the new entity does not define them.
list_tables	Returns a generator to list the tables. The generator will lazily follow the continuation tokens returned by the service and stop when all tables have been returned or num_results is reached. If num_results is specified and the account has more than that number of tables, the generator will have a populated next_marker field once it finishes. This marker can be used to create a new generator if more results are desired.
merge_entity	Updates an existing entity by merging the entity's properties. Throws if the entity does not exist. This operation does not replace the existing entity as the update_entity operation does. A property cannot be removed with merge_entity. Any properties with null values are ignored. All other properties will be updated or added.
query_entities	Returns a generator to list the entities in the table specified. The generator will lazily follow the continuation tokens returned by the service and stop when all entities have been returned or num_results is reached. If num_results is specified and the account has more than that number of entities, the generator will have a populated next_marker field once it finishes. This marker can be used to create a new generator if more results are desired.
set_proxy	Sets the proxy server host and port for the HTTP CONNECT Tunnelling.
set_table_acl	Sets stored access policies for the table that may be used with Shared Access Signatures. When you set permissions for a table, the existing permissions are replaced. To update the table's permissions, call get_table_acl to fetch all access policies associated with the table, modify the access policy that you wish to change, and then call this function with the complete set of data to perform the update. When you establish a stored access policy on a table, it may take up to 30 seconds to take effect. During this interval, a shared access signature that is associated with the stored access policy will throw an <xref:azure.cosmosdb.table.tableservice.AzureHttpError> until the access policy becomes active.
set_table_service_properties	Sets the properties of a storage account's Table service, including Azure Storage Analytics. If an element (ex Logging) is left as None, the existing settings on the service for that functionality are preserved. For more information on Azure Storage Analytics, see https://msdn.microsoft.com/en-us/library/azure/hh343270.aspx.
update_entity	Updates an existing entity in a table. Throws if the entity does not exist. The update_entity operation replaces the entire entity and can be used to remove properties.
