Tim Armstrong created IMPALA-6015:
-------------------------------------
Summary: Simplify ownership of FilterContexts and MemPools in
ScannerContext once non-MT scan node is removed
Key: IMPALA-6015
URL: https://issues.apache.org/jira/browse/IMPALA-6015
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Affects Versions: Impala 2.11.0
Reporter: Tim Armstrong
Priority: Minor
The ownership of these objects is a bit complicated because they can be either
stack-allocated in the scanner thread or owned by a single-threaded scan node .
It should be possible to simplify this once the multithreaded scan node is
removed.
See https://gerrit.cloudera.org/#/c/8025/11/be/src/exec/scanner-context.h@337
for some context.
