>From Wael Alkowaileet <[email protected]>:
Hello Anon. E. Moose #1000171, Jenkins,
I'd like you to reexamine a change. Please visit
https://asterix-gerrit.ics.uci.edu/c/asterixdb/+/12765
to look at the new patch set (#3).
Change subject: [ASTERIXDB-2933][COMP][EXT] Pushdowns Part1: Expected Schema
Node
......................................................................
[ASTERIXDB-2933][COMP][EXT] Pushdowns Part1: Expected Schema Node
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
We want to have a more aggressive pushdown for Parquet. To do so,
we need to compute the expected schema from the expressions in the
query plan. This change introduces the data structure that holds the
expected schema information.
Note:
Moved from asterix-om to asterix-algebra as the expected schema should
not be exposed outside the compiler.
