Tim Armstrong created IMPALA-9126:
-------------------------------------
Summary: Cleanly separate build and probe state in hash join node
Key: IMPALA-9126
URL: https://issues.apache.org/jira/browse/IMPALA-9126
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Reporter: Tim Armstrong
As a precursor to IMPALA-4224, we should clean up the hash join implementation
so that the build and probe state is better separated. The builder should not
deal with probe side data structures (like the probe streams that it allocates)
and all accesses to the build-side data structures should go through as narrow
APIs as possible.
The nested loop join is already pretty clean.
