-----------------------------------
Summary: Support projecting write id as a virtual column for
insert-only transactional tables
Key: IMPALA-11044
URL: https://issues.apache.org/jira/browse/IMPALA-11044
Project: IMPALA
Issue Type: Improvement
Components: Backend, Frontend
Affects Versions: Impala 4.0.0
Reporter: Aman Sinha
For insert-only transactional tables, it would be useful to project the write
id as a virtual column such that partition and/or file pruning can be done
based on the write id. For compacted folders, some thought needs to be given
for what can be projected in order to do a more coarse grained filtering (since
file pruning is not possible after compaction).
