We are experiencing an issue with possibility of tables with _tmp suffix might be dropped.
If you manipulate with a table <X> and there also exist a table with name <X>_tmp, the table <X>_tmp could be accidentally dropped.
These tables (<X> and <X>_tmp) have to be in the same bucket and your project has to have Snowflake backend. We found the root cause and fix will be deployed in 2 hours.
Affected tables will be restored.
2022-08-02 17:00 UTC - We have deployed the fix of this issue and fixed affected tables. The issue is now resolved. We contact affected customers directly.
We are sorry for the inconvenience.
