Dear all, I want to run COMPUTE INCREMENTAL STATS with PARTITION option on some partitions of a partitioned table. It is unclear to me from the documentation if DROP INCREMENTAL STATS must be run on those partitions. For my understanding of how INCREMENTAL STATS with the PARTITION option work, it should not be required, but I've found below sentence on this page https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/impala_perf_stats.html#perf_stats "In cases where new files are added to an existing partition, issue a REFRESH statement for the table, followed by a DROP INCREMENTAL STATS and COMPUTE INCREMENTAL STATS sequence for the changed partition.". I'd prefer to avoid running DROP INCREMENTAL STATS if not required. Does anyone know? Many thanks in advance.
