  • Simplified session msgs to not include low level statement type, only higher level msg type (simple vs extended, etc)
  • Simplified the batch processing on the server session.
  • Rewrote the server session state mgmt
  • Added BEGIN/COMMIT/SYNC to transaction history cache
  • Added session replay for partial transactions (switching from read to write mid transaction).
  • Added session replay for other session after transaction end (when completing a transaction, replay state to other session)

Basic testing done. Need more...
