new 820ec435ce [feature-wip](parquet-reader) refactor parquet_predicate
(#12896)
820ec435ce is described below
commit 820ec435cedcb877f6202194f3f4f0cb5d8e2045
Author: slothever <18522955+w...@users.noreply.github.com>
AuthorDate: Wed Sep 28 21:27:13 2022 +0800
[feature-wip](parquet-reader) refactor parquet_predicate (#12896)
This change serves the following purposes:
1. use ScanPredicate instead of TCondition for external table, it can
reuse old code branch.
2. simplify and delete some useless old code
3. use ColumnValueRange to save predicate
