Summary: Add endpoint coprocessor to speed up queries to backup table (was: Add endpoint coprocessor to speed up queries to hbase:backup table)

> Key: HBASE-16637
> URL: https://issues.apache.org/jira/browse/HBASE-16637
> Project: HBase
> Issue Type: Improvement
> Reporter: Ted Yu
> Labels: backup
>
> Currently BackupSystemTable uses HTable API to query backup table.
> In many scenarios, this is inefficient because filtering is done at client side.
> With more information being recorded in hbase:backup table (such as bulk load descriptor - see HBASE-14417), we should perform filtering on server side.
> An endpoint coprocessor would serve this purpose.
> e.g. without endpoint coprocessor, incremental restore would either bring all bulk load descriptors to client followed by filtering for relevant tables or, issue two queries - one for rows related to the tables being restored and another query to bring down the bulk load descriptors.
