kangkaisen opened a new pull request #2222: Publish version immediately after txt commited
URL: https://github.com/apache/incubator-doris/pull/2222
 
 
   The reason for publish version is slow under high concurrent is:
   
   1. publish version is serial，could not concurrent
   2. publish version need hold the `GlobalTransactionMgr writeLock`
   3. publish version schedule interval is too big
   4. handle publish version task result isn't  timely
   
   This PR improve in 2,3,4 point.
   
   
   Remove the db check when publish, because we will check when finish txn.
   ```
               for (TransactionState transactionState : allCommittedTransactionState) {
                   long dbId = transactionState.getDbId();
                   Database db = catalog.getDb(dbId);
                   if (null == db) {
                       transactionState.setTransactionStatus(TransactionStatus.ABORTED);
                       unprotectUpsertTransactionState(transactionState);
                       continue;
                   }
               }
   ```
