Karan Mehta commented on HBASE-18097:
-------------------------------------
The problem can occur if the client wants results in a specified batch size, in
which case, the results can contain multiple partial results, which is then
left to the user to handle appropriately, based on the {{partial}} flag inside
the result. This is usually the case with AsyncHBaseClient.
> Save bandwidth on partial_flag_per_result in ScanResponse proto

> Key: HBASE-18097
> URL: https://issues.apache.org/jira/browse/HBASE-18097
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 2.0.0, 1.4.0
> Reporter: Karan Mehta
> Assignee: Karan Mehta
>
> Currently the {{ScanResponse}} proto sends out 1 bit per {{Result}} that it
> has embeds inside the {{CellScanner}} to indicate if it is partial or not.
> {code}
> // In every RPC response there should be at most a single partial result.
> Furthermore, if
> // there is a partial result, it is guaranteed to be in the last position
> of the array.
> {code}
> According to client, only the last result can be partial, thus this repeated
> bool can be converted to a bool, thus reducing overhead of serialization and
> deserialization of the array. This will break wire compatibility therefore
> this is something to look for in upcoming versions.
