Parth Chandra updated DRILL-5240: --------------------------------- Labels: ready-to-commit (was: ) > Parquet reader creates unnecessary objects when checking for nullability in > var length columns > ---------------------------------------------------------------------------------------------- > > Key: DRILL-5240 > URL: https://issues.apache.org/jira/browse/DRILL-5240 > Project: Apache Drill > Issue Type: Bug > Components: Storage - Parquet > Reporter: Parth Chandra > Assignee: Parth Chandra > Labels: ready-to-commit > > In {{NullableVarLengthValuesColumn.java}} we have the following line of code: > {code} > currentValNull = > variableWidthVector.getAccessor().getObject(valuesReadInCurrentPass) == null; > {code} > which creates an object to check nullability of every (nullable var char) > value being read. This object creation is expensive and can be replaced with > a simple check for the null bit. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
