Method Details

noPrefix

@BetaApi
public static ParallelCompositeUploadBlobWriteSessionConfig.PartNamingStrategy noPrefix()

Default strategy in which no stable prefix is defined.

General format is

   {randomKeyDigest};{objectInfoDigest};{partIndex}.part
 

{objectInfoDigest} will be fixed for an individual BlobWriteSession.

NOTE:The way in which both randomKeyDigest and objectInfoDigest are generated is undefined and subject to change at any time.

prefix

@BetaApi
public static ParallelCompositeUploadBlobWriteSessionConfig.PartNamingStrategy prefix(String prefixPattern)

Strategy in which an explicit stable prefix is present on each part and intermediary compose object.

General format is

   {prefixPattern}/{randomKeyDigest};{objectInfoDigest};{partIndex}.part
 

{objectInfoDigest} will be fixed for an individual BlobWriteSession.

NOTE:The way in which both randomKeyDigest and objectInfoDigest are generated is undefined and subject to change at any time.

Care must be taken when choosing to specify a stable prefix as this can create hotspots in the keyspace for object names. See Object Naming Convention Guidelines for more details.
