## Proposed changes
in query rewrite by mv, we want know the mv rewrite process info
such as materializedView used by rewrite, which materializedView rewrite
success, and
chosen which materializedView by cost finally.
explain memo plan as <query _sql>
materializedView rewrite is under the **MATERIALIZATIONS**, example as
following:
we can see the mv2_0 materializedView is rewritten successfuly and chosen
finally.
and mv2_1 and mv2_2 is failed with fali reason.
> ========== MATERIALIZATIONS ==========
materializationContexts:
> MaterializationContext[mv2_0] ( rewriteSuccess=true, failReason=[
> ] )
> MaterializationContext[mv2_1] ( rewriteSuccess=false, failReason=[
