    Journal log store for transaction logs

      In the latest JBoss EAP 7.1 PERFORMANCE TUNING GUIDE under Transactions Subsystem Tuning it says:


      "For better XA transaction performance, it is recommended that you use a journal log store...

      Especially for XA transactions, a journal store is much more efficient as it uses a journal that consists of one file for all transactions"


      What is this journal log store that uses a single file for the whole log instead of a single file for each log entry? Is it part of Narayana? It doesn't seem to be present under Narayana source code.
