Summary0000952: Data can be skipped due to aggressive purge on some platforms
DescriptionMySQL uses the max data_id as the next data_id.

If rows 5,6,7,8,9,10 are purged and the next data_id was going to be 11, sym_data_gap would have a gap of 11 to 50,000. The next data_id inserted will be 5 because 5-10 have been purged. data_ids 5-10 will never be routed.

Maybe the solution is to never purge the last data_id?
