Thomas Weise commented on APEXMALHAR-2193:
------------------------------------------

These are all things that were solved in HDHT so we should look there. Since these are not
cheap collections (even though they are made look cheap), we really need to understand what
happens at the storage layer. It should not actually delete or update immediately but changes
go into a write buffer which gets periodically flushed. Please check how managed state works
and that it is used correctly.
