Parth Chandra created DRILL-5240:
------------------------------------
Summary: 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
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.
