Hanisha Koneru updated HDDS-284:
--------------------------------
Description:
This Jira is to add CRC for chunks data.
Right now a Chunk Info structure looks like this:
_message ChunkInfo {_
_required string chunkName =_ _1__;_
_required uint64 offset =_ _2__;_
_required uint64 len =_ _3__;_
_optional string checksum =_ _4__;_
_repeated KeyValue metadata =_ _5__;_
_}_
_Proposal is to change ChunkInfo structure as below:_
_message ChunkInfo {_
_required string chunkName =_ _1__;_
_required uint64 offset =_ _2__;_
_required uint64 len =_ _3__;_
_optional bytes checksum =_ _4__;_
_optional CRCType checksumType =_ _5__;_
_optional string legacyMetadata =_ _6__;_
_optional string legacyData =_ _7__;_
_repeated KeyValue metadata =_ _8__;_
_}_
_Instead of changing disk format, we put the checksum, checksumtype and legacy
data fields in to chunkInfo._
