>From Wael Alkowaileet <[email protected]>:
Hello Jenkins,
I'd like you to reexamine a change. Please visit
https://asterix-gerrit.ics.uci.edu/c/asterixdb/+/12964
to look at the new patch set (#3).
Change subject: [ASTERIXDB-2933][COMP][EXT] Pushdowns Part2: Pushdown Rule
......................................................................
[ASTERIXDB-2933][COMP][EXT] Pushdowns Part2: Pushdown Rule
- user model changes: no
- storage format changes: no
- interface changes: yes
Details:
Add a rule that computes the expected schema and sets it
to the DataSourceScanOperator. The computed schema is then
passed to the Parquet Reader to 'clip' the Parquet file's
schema. The resulting clipped schema is then used to tell
the reader what column should be read.
Interface changes:
- Change IProjectionInfo<List<T>> to IProjectionInfo<T>
