[Labs-l] Query results are inconsistent between DBs

[Jaime Crespo]

Huji Lee,


Thank you for the report. May I ask you to please, please write a
phabricator ticket with the projects "DBA", so we make sure our "one
and only DBA" does not forget about this issue.

Please include the query, host, database, expected results and actual
results, both in production (API) and labs replicas.

Thank you!
