Sameer Agarwal updated SPARK-22739: ----------------------------------- Priority: Critical (was: Major) > Additional Expression Support for Objects > ----------------------------------------- > > Key: SPARK-22739 > URL: https://issues.apache.org/jira/browse/SPARK-22739 > Project: Spark > Issue Type: New Feature > Components: SQL > Affects Versions: 2.3.0 > Reporter: Aleksander Eskilson > Priority: Critical > > Some discussion in Spark-Avro [1] motivates additions and minor changes to > the {{Objects}} Expressions API [2]. The proposed changes include > * a generalized form of {{initializeJavaBean}} taking a sequence of > initialization expressions that can be applied to instances of varying objects > * an object cast that performs a simple Java type cast against a value > * making {{ExternalMapToCatalyst}} public, for use in outside libraries > These changes would facilitate the writing of custom encoders for varying > objects that cannot already be readily converted to a statically typed > dataset by a JavaBean encoder (e.g. Avro). > [1] -- > https://github.com/databricks/spark-avro/pull/217#issuecomment-342599110 > [2] -- > > https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/objects/objects.scala -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
