>                 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
> 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,
>     // there is a partial result, it is guaranteed to be in the last position of the
> {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
