--------------------------------------
Summary: Paged server side grouped aggregate operations
Key: PHOENIX-6207
URL: https://issues.apache.org/jira/browse/PHOENIX-6207
Project: Phoenix
Issue Type: Improvement
Affects Versions: 4.14.3, 5.0.0
Reporter: Kadir OZDEMIR
Assignee: Kadir OZDEMIR
Phoenix provides the option of performing query operations on the client or
server side. This is decided by the Phoenix optimizer based on configuration
parameters. For the server side option, the table operation is parallelized
such that multiple table regions are scanned. However, currently there is no
paging capability and the server side operation can take long enough lead to
HBase client timeouts. Putting a limit on the number of rows to be processed
within a single RPC call (i.e., the next operation on the scanner) on the
server side using a Phoenix level paging is highly desirable. This paging
mechanism has been already implemented for index rebuild and verification
operations and proven to be effective to prevent timeouts. This Jira is for
implementing this paging for the server side grouped aggregate operations.
