Unlike RPC, calls addressed to rows > or ranges of rows. Coprocessor client library resolves to actual locations. > Calls across multiple rows automatically split into multiple parallelized > RPCs" > Generic multicall RPC facility which incorporates this and > multiget/multiput/multidelete and parallel scanners. > Group and batch RPCs by region server. Track and retry outstanding RPCs. Ride > over region relocations. > Support addressing by explicit region identifier or by row key or row key > range. > Include a facility for merging results client side. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
