Apache Spark reassigned SPARK-5738: ----------------------------------- Assignee: (was: Apache Spark) > Reuse mutable row for each record at jsonStringToRow > ---------------------------------------------------- > > Key: SPARK-5738 > URL: https://issues.apache.org/jira/browse/SPARK-5738 > Project: Spark > Issue Type: Sub-task > Components: SQL > Affects Versions: 1.3.0 > Reporter: Yanbo Liang > > Other table scan like operations include ParquetTableScan, HiveTableScan use > a reusable mutable row for seralization to decrease garbage. We also make > JSONRelation#buildScan() with this optimization. > When serialize json string to row, reuse a mutable row for both each record > and inner nested structure instead of creating a new one for each. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
