Reynold Xin created SPARK-18522: ----------------------------------- Summary: 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
