Bryan Cutler commented on SPARK-21583: -------------------------------------- I have this implemented already, will submit a PR soon. > Create a ColumnarBatch with ArrowColumnVectors for row based iteration > ---------------------------------------------------------------------- > > Key: SPARK-21583 > URL: https://issues.apache.org/jira/browse/SPARK-21583 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.3.0 > Reporter: Bryan Cutler > > The existing {{ArrowColumnVector}} creates a read-only vector of Arrow data. > It would be useful to be able to create a {{ColumnarBatch}} to allow row > based iteration over multiple {{ArrowColumnVectors}}. This would avoid extra > copying to translate column elements into rows and be more efficient memory > usage while increasing performance. -- 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
