Hi Mingmin
Sorry, the meeting was in the middle of the night for me and I wasn't able to
make it.
The timing and checklist look good to me.
We plan to do a Beam release end of June, so, merging in July means we can
include it in the next release.
Thanks !
Regards
JB

Hi all,
Thanks to join the meeting. As discussed, we're planning to merge DSL_SQL
branch back to master, targeted in the middle of July. A tag
'dsl_sql_merge'[1] is created to track all todo tasks.
