Subject [jira] [Created] (HIVE-16565) Improve how the open transactions and aborted transactions are deserialized in ValidReadTxnList.readFromString
Date Mon, 01 May 2017 21:39:04 GMT
Wei Zheng created HIVE-16565:
--------------------------------

             Summary: Improve how the open transactions and aborted transactions are deserialized
in ValidReadTxnList.readFromString
                 Key: HIVE-16565
                 URL: https://issues.apache.org/jira/browse/HIVE-16565
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 3.0.0
            Reporter: Wei Zheng
            Assignee: Wei Zheng


This is a follow-up of HIVE-16534.

In ValidReadTxnList.writeToString, we write out two open and aborted transactions as two sorted
lists. We can take advantage of that and perform merge sort them together when reading them
back in readFromString. Note that the aborted bits should also be handled properly during
the merge sort.
