A transaction record (Commit or Prepare), will hold the number of elements the transaction has in the current file.
While loading the {@link JournalFile}, the number of operations found is matched against this number. If for any reason there are missing operations, the transaction will be ignored.
We can't just use a global counter as reclaiming could delete files after the transaction was successfully committed. That also means not having a whole file on journal-reload doesn't mean we have to invalidate the transaction
The commit operation itself is not included in this total. @author Clebert Suconic
