Lars Volker has uploaded a new patch set (#5). Change subject: IMPALA-2521: Add clustered hint to insert statements ......................................................................
IMPALA-2521: Add clustered hint to insert statements This change introduces a clustered/noclustered hint for insert statements. Specifying this hint adds an additional sort node to the plan, just before the table sink. This has the effect that data will be clustered by its partition prior to writing partitions, which therefore can be written sequentially.
