MaximumBlobSizeBeforeTransmittingAsBlocks

public static long MaximumBlobSizeBeforeTransmittingAsBlocks

When transmitting a blob that is larger than this constant, this library automatically transmits the blob as individual blocks. I.e., the blob is (1) partitioned into separate parts (these parts are called blocks) and then (2) each of the blocks is transmitted separately. The maximum size of this constant as supported by the real blob storage service is currently 64 MB; the development storage tool currently restricts this value to 2 MB. Setting this constant can have a significant impact on the performance for uploading or downloading blobs. As a general guideline: If you run in a reliable environment increase this constant to reduce the amount of roundtrips. In an unreliable environment keep this constant low to reduce the amount of data that needs to be retransmitted in case of connection failures.

BlockSize

public static long BlockSize

The size of a single block when transmitting a blob that is larger than the MaximumBlobSizeBeforeTransmittingAsBlocks constant (see above). The maximum size of this constant is currently 4 MB; the development storage tool currently restricts this value to 1 MB. Setting this constant can have a significant impact on the performance for uploading or downloading blobs. As a general guideline: If you run in a reliable environment increase this constant to reduce the amount of roundtrips. In an unreliable environment keep this constant low to reduce the amount of data that needs to be retransmitted in case of connection failures.

GenerateBlockMD5

public static boolean GenerateBlockMD5

Generate content md5 for each block when uploading large blob.
