Summary: Cache merged column stats from retrieved partitions Key: HIVE-17265 URL: https://issues.apache.org/jira/browse/HIVE-17265 Project: Hive Issue Type: Bug Components: Statistics Affects Versions: 3.0.0 Reporter: Jesus Camacho Rodriguez Assignee: Jesus Camacho Rodriguez Currently when we retrieve stats from the metastore for a column in a partitioned table, we will execute the logic to merge the column stats coming from each partition multiple times. Even though we avoid multiple calls to metastore if the cache for the stats in enabled, merging the stats for a given column can take a large amount of time if there is a large number of partitions. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
