DB Number Restriction | Each instance supports 256 DBs. Description l The total amount of data stored in all DBs is limited by the memory size of the instance; l the memory used by a single DB is automatically assigned according to usage, and the upper limit is the instance memory (for instance, if DB0 occupies all the memory, there will be no data in the rest of the DBs). |
Expired Data Deletion Policy | The lazy deletion policy is used by default. When a user accesses a key and the key has expired, it will be deleted. |
