Hello Michael Smith, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/24870
to look at the new patch set (#2).
Change subject: IMPALA-15334: Decompose unrewritable CTE suggestions to explore
more rewrites
......................................................................
IMPALA-15334: Decompose unrewritable CTE suggestions to explore more rewrites
In some cases the suggester returns CTEs that are not rewritable (cannot
be used by the rewrite algorithm). Although, the entire CTE may not be
rewritable parts of it are so by decomposing it further we can find more
sharing opportunities.
The commits adds MaterializedViewSubTreeSplitter to decompose a plan
into maximal rewritable trees following the limitations imposed by
Calcite's materialized view rules.
