Yongjin Choi commented on TAJO-1537:
------------------------------------
The virtual table name is 'session'.
The example of this is as follows.
{code:sql}
yjchoi:~$ tsql
default> select * from information_schema.session;
session_id, username, current_db, last_access_time

> Implement a virtual table for sessions
> --------------------------------------
>
> Key: TAJO-1537
> URL: https://issues.apache.org/jira/browse/TAJO-1537
> Project: Tajo
> Issue Type: New Feature
> Components: tajo master
> Reporter: Yongjin Choi
> Assignee: Yongjin Choi
> Priority: Minor
>
> Most databases provide a way to get information about active sessions (e.g.,
> pg_stat_activity in postgresql, processlist in mysql, v$session in oracle,
> and so on).
> But, tajo does not have such table yet.
> Implementing session virtual table would be helpful to monitoring and
> administration.
