> _required CRCTYPE crcType =_ _2__;_
> _optional String LegacyMetadata = 3; // Fields to support inplace data
> migration_
> _optional String LegacyData = 4;_
> _optional ushort ChecksumblockSize = 5; // Size of the block used to compute
> the checksums_
> _repeated uint32 checksums = 6 ; // Set of Checksums_
> *_repeated byte data = 6;_* _// Actual Data stream_
>
> _}_
