Description

See discussion in thread: https://lists.apache.org/thread.html/b992db7e843e1444d2c4835ac9ece41bee2b251a60785d8881452b95@%3Cusers.jena.apache.org%3E

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.
