When running archival jobs, use the dataarchival/dailyLimitPerPolicy setting to change the rate at which you archive eligible cases.
When running purge jobs, use the dataarchival/purgeQueryLimit to change the rate at which a subquery deletes records.
- Plan to run your archive and purge jobs at an initial faster rate to clear your
- Find out the number of cases in your initial backlog and the rate at which cases become eligible for archiving.
- Determine a period of low-system load, then schedule an archive and
purge process that finishes during that time period.
For example, your system might experience low system load every day for five hours or every weekend for 12 hours.
For more information, see Scheduling the case archival process.
- Determine how high your rate of archiving and purge can go by
performing an experiment:
- Start the experiment by setting a low rate in the dataarchival/dailyLimitPerPolicy and dataarchival/purgeQueryLimit dynamic system settings, respectively.
- Run a process with the following jobs with the low value for the
number of cases:
For more information, see Case archiving and purging overview.
- Monitor the progress of your case archiving process. For more information about monitoring the progress of your case archiving process, see Monitoring the progress of your case archival process.
- Determine the performance impact and time that this low rate of archive and purge process takes.
- Run the archiving process again with an increased rate of
archiving and purging.
A faster rate of archiving impacts system resources more and takes longer to complete.
- Continue to increase the rate to determine a maximum that completes the process within the low system load duration and within an acceptable system impact.
- Clear your backlog by using the maximum rate found above. The maximum rate of archiving and purging determines the time frame for clearing your backlog.
- Adjust the archiving and purging process after clearing your backlog.
- If your current rate of archiving and purging meets or exceeds the rate at which cases become eligible for archiving, keep that archiving rate.
- If your current rate of archiving is slower than the rate at which cases become eligible for archiving, plan to run your archival and purge jobs more frequently to archive faster.
