Hi,

1. The property "oozie.service.PurgeService.purge.limit" defines the number
of records to be retrieved/deleted in each operation with the database.

2. It is just not to overload the database with purge service operation
data in a single transaction.

3. The logs of the PurgeService are written in the oozie.log file only. By
default it executes every hour.

Thanks,
Abhishek
