Ji Liu closed FLINK-12349. -------------------------- Resolution: Invalid > [Java] Improve performance of BaseValueVector#getValidityBufferSizeFromCount > ---------------------------------------------------------------------------- > > Key: FLINK-12349 > URL: https://issues.apache.org/jira/browse/FLINK-12349 > Project: Flink > Issue Type: Improvement > Reporter: Ji Liu > Assignee: Ji Liu > Priority: Trivial > > Now in _BaseValueVector#getValidityBufferSizeFromCount_ and > _BitVectorHelper#getValidityBufferSize_, it uses _Math.ceil_ to calculate > size which is not efficient (lots of unnecessary logic in > _StrictMath#floorOrCeil_) since the value count is always not less than 0, we > could simply replace Math.ceil with the following code: > _return valueCount % 8 > 0 ? valueCount / 8 + 1 : valueCount / 8;_ -- This message was sent by Atlassian JIRA (v7.6.3#76005)
