Limitations / Known Issues

Block Cache

  • Concurrent write operations to the same file from multiple handles in the same replica, or from different replicas, may lead to data corruption.
  • In write operations, data is persisted to the Azure storage account only when close, sync or flush is called.
  • Cached data blocks are not refreshed when the file size remains unchanged after a write operation by another process.

File Cache

  • Ensure that Attribute Cache is disabled when using file cache, as an issue/bug with the driver prevents eviction of cached data when the file is opened more frequently than the defined timeout.
