--------------------------------
Summary: Enable every column stat when storing a table
Key: TAJO-1120
URL: https://issues.apache.org/jira/browse/TAJO-1120
Project: Tajo
Issue Type: Improvement
Components: catalog
Reporter: Jihoon Son
Assignee: Jihoon Son
Fix For: 0.9.1
Currently, the number of null values and the max/min values of a column are
collected only in the shuffle stage.
In addition, the number of distinct values of a column seems not to be
collected in anywhere.
However, some recent issues such as TAJO-838 and TAJO-1091 require these
statistics, and thus we need to collect them for tables that are newly stored
via CTAS or INSERT INTO statements.
