@rajrahul this link is good. As expected, the int96 column is dictionary
encoded.
Is it possible for you to extract just a couple of records from this file
and then use that for a unit test?
see
[TestParquetWriter.testImpalaParquetBinaryAsTimeStamp_DictChange](https://github.com/apache/drill/blob/master/exec/java-exec/src/test/java/org/apache/drill/exec/physical/impl/writer/TestParquetWriter.java#L784)
@vdiravka TestParquetWriter.testImpalaParquetBinaryAsTimeStamp_DictChange
also uses an int96 that is dictionary encoded. Any idea whether (and why) it
might be going thru a different code path?
