The 2019-02-02 Azure Storage version includes the following features and updates:

  • A new API, Blob Batch, allows multiple requests to be sent within a single request body.

  • Data transfer APIs accept CRC64 as a transactional data-integrity mechanism as an alternative to MD5. Note that this calculation requires a specific polynomial.

  • Responses for all Azure Blob Storage, Azure Table Storage, and Azure Queue Storage APIs return the x-ms-client-request-id that was passed in thanks to requests for better code debugging.

  • You can encrypt data by using a Customer-Provided Key or an Encryption Scope.

  • The Copy Blob, Put Block List, and Put Blob APIs support the x-ms-access-tier header for block blobs, to set the tier on the result without needing a second API call.

  • The Copy Blob and Set Blob Tier APIs support the x-ms-rehydrate-priority header to allow for faster retrieval of archived blobs.

  • A new Create Permission API lets you create a security descriptor at the file share level. This descriptor can be used for files and directories in the share.

  • A new Get Permission API lets you retrieve the security descriptor that's set on a share.

  • A new Lease File SPI gives you an exclusive write lock lease on a file to be acquired, changed, released, or broken.

  • Certain Azure Files APIs (Set Directory Properties, Set File Properties, Create File, and Create Directory) require a new set of headers. These headers are x-ms-file-permission, x-ms-file-permission-key, x-ms-file-attributes, x-ms-file-creation-time and x-ms-file-last-write-time. These headers are also returned on the corresponding Get APIs.
