Problem Description:
Purge outdated entries of indexes inside IBM IRIS Safer Payments does not support the concept of span control to limit the scope of removal of all index entries that are older than a defined maximum lifetime period.
Supporting Details/Description:
The IBM Safer Payments uses a fully automated system for cleaning outdated entries within the limit of maximum lifetime. The lack of limiting the scope of entries to clean does not allow for IBM Safer Payments user control closing the Start End of Day (EoD) job before high traffic time, as the procedure does not stop until it completes purging whole data. For example: The amount of records marked for purging by the system is 50 million, the Start End of Day (EoD) job does not stop until it deletes all unnecessary data, and IBM Safer Payments enters the high traffic period with job running.
Recommended solution:
Customizing the number of entries to be purged will solve the crucial issue. With proper analysis and configuration, closing the task Start End of Day (EoD) job before peak load period is guaranteed and index will not intensely increase in size without creating unwanted load on CPU.

Wouldn't it be better to define some defined "high traffic" timeframe which has no purging and no eod at all? - The period when there is no high traffic is analyzed and eod starts at this time, but the period is not enough to finish purging. You can not define high traffic timeframe when it work real-time, in that case IBM Safer Payments will catch potentially fraud transactions in defined timeframe!
Limiting the number of purged records might be a solution but it wouldn't actually guarantee to finish the eod job before peak load -for example if there are other disk operations that slow down the purging of index entries.- When EOD starts, that specific instance is isolated and other operation are stopped. Of course, it is not guaranteed that job will not be finished, but is there any better solution?
