Apache Spark commented on SPARK-13574: -------------------------------------- User 'nongli' has created a pull request for this issue: https://github.com/apache/spark/pull/11454 > Improve parquet dictionary decoding for strings > ----------------------------------------------- > > Key: SPARK-13574 > URL: https://issues.apache.org/jira/browse/SPARK-13574 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Nong Li > Priority: Minor > > Currently, the parquet reader will copy the dictionary value for each data > value. This is bad for string columns as we explode the dictionary during > decode. We should instead, have the data values point to the safe backing > memory. -- 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
