[I] Define timestamp ordering for int96 timestamp columns [parquet-format]
rahulketch opened a new issue, #502:
URL: https://github.com/apache/parquet-format/issues/502
### Describe the enhancement requested
int96 is used as the default timestamp in spark. Timestamp filters are extremely common and lack of ordering and stats limit optimization opportunities
