Wes McKinney commented on ARROW-1833:
-------------------------------------
See
[https://github.com/apache/arrow/blob/master/java/vector/src/main/java/org/apache/arrow/vector/SmallIntVector.java#L125]
In some applications, if the null count of a vector is 0, users could use a
method like {{getObjectDirty}} (not sure what to call it) to get the value from
the slot in the {{ArrowBuf}} without calling {{isSet}}. This would yield better
performance for iterating over the values in a vector without nulls, such as
one obtained from a Parquet file with a non-nullable (REQUIRED repetition level
column)
