Andy Seaborne commented on JENA-1222:
-------------------------------------
The size of the journal may also be measured in length for the case when many
writers happen without the journal being able to write back. At some time,
lock out new transactions and wait to flush the journal when it has many layers
in it.
> Control the flushing of the commit log based on journal size.

> TDB batches commits to save on overheads of small updates. However, if the
> application is continually making large commits then batching saves little,
> and causes more temporary resource consumption (RAM especially). It may also
> cause jitters in performance due to a large updates to the main database.
