Hi,

We are encountering an abnormal behavior of data after purging DAS table
using analytics backup tool kit [1], -purge command.

To reproduce this issue,

   1. Generate a table (x) from spark script using y table.
   2. Purge all the data in x using analytics backup tool command -purge.
   3. Re-populate the table x as in 1.
   4. Send events to stream y (Execution plan will refer to table x when
   you send events to y)
   5. Now if you see the table x, it will be empty.

Thanks.

Regards,
Vithulan.
