> table/partition level statistics
> --------------------------------
>
> Key: HIVE-1361
> URL: https://issues.apache.org/jira/browse/HIVE-1361
> Project: Hadoop Hive
> Issue Type: Sub-task
> Affects Versions: 0.6.0
> Reporter: Ning Zhang
> Assignee: Ahmed M Aly
> Attachments: HIVE-1361.java_only.patch, HIVE-1361.patch, stats0.patch
>
>
> At the first step, we gather table-level stats for non-partitioned table and
> partition-level stats for partitioned table. Future work could extend the
> table level stats to partitioned table as well.
> There are 3 major milestones in this subtask:
> 1) extend the insert statement to gather table/partition level stats
> on-the-fly.
> 2) extend metastore API to support storing and retrieving stats for a
> particular table/partition.
> 3) add an ANALYZE TABLE [PARTITION] statement in Hive QL to gather stats for
> existing tables/partitions.
> The proposed stats are:
> Partition-level stats:
> - number of rows
> - total size in bytes
> - number of files
> - max, min, average row sizes
> - max, min, average file sizes
> Table-level stats in addition to partition level stats:
> - number of partitions
