-------------------------------
Summary: Code Refactoring, Test Case Improvement and Description
Updates for SQLConf spark.sql.parquet.filterPushdown
Key: SPARK-16010
URL: https://issues.apache.org/jira/browse/SPARK-16010
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.0.0
Reporter: Xiao Li
Starting Spark 2.0, vectorized decoding is introduced for parquet reading. This
feature changes the filter pushdown behavior of parquet reading. Thus, we need
to update the out-of-dated description of two external `SQLConf`:
`spark.sql.parquet.filterPushdown` and
`spark.sql.parquet.enableVectorizedReader`.
The code for building `parquetReader` can be slightly simplified for easy
maintenance.
The current test cases do not verify the behavior when
`spark.sql.parquet.filterPushdown` is set to `false`, a test case for improving
the test case coverage.
