[jira] [Created] (ARROW-5903) [Java] Set methods in DecimalVector are slow

Pindikura Ravindra created ARROW-5903:
-----------------------------------------

             Summary: [Java] Set methods in DecimalVector are slow
                 Key: ARROW-5903
                 URL: https://issues.apache.org/jira/browse/ARROW-5903
             Project: Apache Arrow
          Issue Type: Task
          Components: Java
            Reporter: Pindikura Ravindra
            Assignee: Pindikura Ravindra


The methods are doing a bound check on each byte in the input buffer and each byte on the output buffer. Avoiding this repetitive work improves perf by a factor of 2x to 3x.
