Subject [jira] [Commented] (TAJO-284) Add table partitioning entry to Catalog
Date Mon, 18 Nov 2013 02:59:20 GMT

    [ https://issues.apache.org/jira/browse/TAJO-284?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13825049#comment-13825049

Hyunsik Choi commented on TAJO-284:
-----------------------------------

If EXPRESSIONS contains all partitions as you mentioned, it cannot contain a number of partitions
and cannot utilize the indexing techniques of underlying RDBMS. In my opinion, each partition
should be one row.

> To support table partitioning, Tajo catalog should supports the table partitioning. Each
partition entry should include partition table id, partition key ids, partition types (i.e.,
hash, range, list, and key), partition number, min, max, and hash id.
