> INFORMATION_SCHEMA usability: difficult to access # of table records
> --------------------------------------------------------------------
>
> Key: HIVE-16938
> URL: https://issues.apache.org/jira/browse/HIVE-16938
> Project: Hive
> Issue Type: Bug
> Reporter: Carter Shanklin
> Assignee: Gunther Hagleitner
> Attachments: HIVE-16938.1.patch, HIVE-16938.2.patch
>
>
> HIVE-1010 adds an information schema to Hive, also taking the opportunity to
> expose some non-standard but valuable things like statistics in a SYS table.
> One common thing users want to know is the number of rows in tables, system
> wide.
> This information is in the table_params table but the structure of this table
> makes it quite inconvenient to access since it is essentially a table of
> key-value pairs. More table stats are likely to be added over time,
> especially because of ACID. It would be a lot better if this were a first
> class table.
> For what it's worth I deal with the current table by pivoting it into
> something easier to deal with as follows:
> {code}
> create view table_stats as
> select
> tbl_id,
> max(case param_key when 'COLUMN_STATS_ACCURATE' then param_value end) as
> COLUMN_STATS_ACCURATE,
> max(case param_key when 'numFiles' then param_value end) as numFiles,
> max(case param_key when 'numRows' then param_value end) as numRows,
> max(case param_key when 'rawDataSize' then param_value end) as rawDataSize,
> max(case param_key when 'totalSize' then param_value end) as totalSize,
> max(case param_key when 'transient_lastDdlTime' then param_value end) as
> transient_lastDdlTime
> from table_params group by tbl_id;
> {code}
> It would be better to not have users provide workarounds and make table stats
> first-class like column stats currently are.
