Apache Spark reassigned SPARK-18522: ------------------------------------ Assignee: Reynold Xin (was: Apache Spark) > Create explicit contract for column stats serialization > ------------------------------------------------------- > > Key: SPARK-18522 > URL: https://issues.apache.org/jira/browse/SPARK-18522 > Project: Spark > Issue Type: Sub-task > Components: SQL > Reporter: Reynold Xin > Assignee: Reynold Xin > > The current implementation of column stats uses the base64 encoding of the > internal UnsafeRow format to persist statistics (in table properties in Hive > metastore). This is an internal format that is not stable across different > versions of Spark and should NOT be used for persistence. > In addition, it would be better if statistics stored in the catalog is human > readable. -- 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
