Thomas Graves commented on SPARK-24934:
---------------------------------------
what is the real affected versions here? Since it went into spark 2.3.2 does
it affect 2.3.1?
> Complex type and binary type in in-memory partition pruning does not work due
> to missing upper/lower bounds cases

> Key: SPARK-24934
> URL: https://issues.apache.org/jira/browse/SPARK-24934
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Hyukjin Kwon
> Assignee: Hyukjin Kwon
> Priority: Critical
> Labels: correctness
> Fix For: 2.3.2, 2.4.0

>
> For example, if array is used (where the lower and upper bounds for its
> column batch are {{null}})), it looks wrongly filtering all data out:
> {code}
> scala> import org.apache.spark.sql.functions
> import org.apache.spark.sql.functions
> scala> val df = Seq(Array("a", "b"), Array("c", "d")).toDF("arrayCol")
> df: org.apache.spark.sql.DataFrame = [arrayCol: array<string>]
> scala>
> df.filter(df.col("arrayCol").eqNullSafe(functions.array(functions.lit("a"),
> functions.lit("b")))).show()
> +--------+
> |arrayCol|
> +--------+
> | [a, b]|
> +--------+
> scala>
> df.cache().filter(df.col("arrayCol").eqNullSafe(functions.array(functions.lit("a"),
> functions.lit("b")))).show()
> +--------+
> |arrayCol|
> +--------+
> +--------+
> {code}
