Hi, Rick.
There is no problem with dropping the oldest records by truncating and reorganize partitions. It works good and fast.
But the same time we need to do a lot of deletes "in the middle" of table. So we need to do periodical OPTIMIZE for selected partitions.
This table is heavily loaded for write operations. Optimizing one partition can take several minutes. So table (or this partition) is locked for this time.
The idea is to optimize selected subpartitions. This will not take a lot of time because their size is small.
