Hi Brian, Unfortunately Kudu partitions must be pre-defined as you suspected, so the Oracle syntax you described won't work for Impala. However, you can add and drop range partitions even after the table is created, so you can manually add the next hour/day/week partition, and drop some historical partition. The syntax is described in the latest version of the CDH documentation: https://www.cloudera.com/documentation/enterprise/latest/topics/impala_kudu.html#kudu_range_partitioning Best, Matt
