Artem Kupchinskiy updated SPARK-33689: -------------------------------------- Summary: ArrayData specialization to enable RowEncoder primitive arrays support (was: RowEncoder primitive arrays support) > ArrayData specialization to enable RowEncoder primitive arrays support > ---------------------------------------------------------------------- > > Key: SPARK-33689 > URL: https://issues.apache.org/jira/browse/SPARK-33689 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.0.1 > Reporter: Artem Kupchinskiy > Priority: Major > > Currently, even non-nullable array fields are represented as > WrappedArray.ofRef in external rows. It leads to memory footprint, as well as > unnecessary cycles in boxing/unboxing operations. Ideally, if arrays are > non-nullable and contain primitive values, they should be represented as > specialized less-overhead versions of WrappedArray. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
