----------------------------------------
Summary: Pushdown predicates for Parquet external datasets too
filter row groups
Key: ASTERIXDB-3575
URL: https://issues.apache.org/jira/browse/ASTERIXDB-3575
Project: Apache AsterixDB
Issue Type: Improvement
Components: EXT - External data
Reporter: Peeyush Gupta
Parquet files contain min-max values for each column for each row group. This
information can be used to filter out row groups based on the predicates used
in the query.
We should pushdown predicates to external data scan for parquet to filter out
row groups.
