> Key: SPARK-32351
> URL: https://issues.apache.org/jira/browse/SPARK-32351
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Yuming Wang
> Assignee: pavithra ramachandran
> Priority: Major
> Fix For: 3.1.0
>
>
> How to reproduce this issue:
> {code:scala}
> spark.sql(
> s"""
> |CREATE TABLE t(i INT, p STRING)
> |USING parquet
> |PARTITIONED BY (p)""".stripMargin)
> spark.range(0, 1000).selectExpr("id as col").createOrReplaceTempView("temp")
> for (part <- Seq(1, 2, 3, 4)) {
> sql(s"""
> |INSERT OVERWRITE TABLE t PARTITION (p='$part')
> |SELECT col FROM temp""".stripMargin)
> }
> spark.sql("SELECT * FROM t WHERE WHERE (p = '1' AND i = 1) OR (p = '2' and i
> = 2)").explain
> {code}
> We have pushed down {{p = '1' or p = '2'}} since SPARK-28169, but this pushed
> down filter not in explain
> {noformat}
> == Physical Plan ==
> *(1) Filter (((p#21 = 1) AND (i#20 = 1)) OR ((p#21 = 2) AND (i#20 = 2)))
> +- *(1) ColumnarToRow
> +- FileScan parquet default.t[i#20,p#21] Batched: true, DataFilters: [],
> Format: Parquet, Location:
> InMemoryFileIndex[file:/Users/yumwang/spark/SPARK-32289/sql/core/spark-warehouse/org.apache.spark...,
> PartitionFilters: [], PushedFilters: [], ReadSchema: struct<i:int>
> {noformat}
