Changes to ticket per email – so, this ticket would be about wiredTigerMaxCacheOverflowSizeGB
Will not need to do wiredTigerMaxHistoryFileSizeGB as that has been eliminated.
Today, we have made another change that makes the LAS cache file limit parameter ("wiredTigerMaxCacheOverflowSizeGB") a hidden option with no effect in version 4.4. In addition, we eliminated the new parameter mentioned in the previous downstream changes email that was going to limit the size of the WiredTiger history file ("wiredTigerMaxHistoryFileSizeGB"),because this functionality would not provide a good solution for users who desired the same behavior as for the cache file limit option. Dima, you raised some good questions here and we decided that we did not have satisfactory answers with the existence of this new option.
Please reach out to Brian Lane if anyone has concerns or questions about this new change.
The WiredTiger cache overflow file has been removed in 4.4, so this configuration option doesn't make work any more - we should deprecate it. There are a number of users who set this configuration option - so we should be nice to them when doing this work.
