Subject [jira] [Created] (DRILL-6493) Replace BitVector with Uint1Vector
Date Wed, 13 Jun 2018 18:29:00 GMT
Karthikeyan Manivannan created DRILL-6493:

             Summary: Replace BitVector with Uint1Vector
                 Key: DRILL-6493
                 URL: https://issues.apache.org/jira/browse/DRILL-6493
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Karthikeyan Manivannan

BitVector stores a single bit of data and it uses a bit of storage space. UInt1 is an alternate
implementation which uses a byte to store a bit. Recently discovered bugs in BitVector and
anecdotal evidence of performance issues seems to suggest that this code is slow and buggy.
I am opening this bug to analyze the impact of replacing BitVector with UInt1.
