Ji Liu created FLINK-12349: ------------------------------ Summary: [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
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)
