    Description

      Currently, deleting a storage group requires waiting for all corresponding memtables to flush to disks. This may take a lot of time. Experiments show that deleting all storage groups takes more than two minutes when the memory usage is 150GB. In fact, we might be able to drop the corresponding memtable in memory and let the JVM GC it.
