Log type of DROP STORAGE operation. More...

Detailed Description

Log type of DROP STORAGE operation.

This log corresponds to StorageManager::drop_storage() opereation. DROP STORAGE has no in-epoch transaction order. It is always processed in a separate epoch from operations for the storage. Thus, we advance epoch before and after dropping a storage.
