Query DB key counts
Usage is db.
You can query the total key count and the count by data type.
From Ent 8.1.0, keys are stored by data type, so key counts by type can be queried quickly.
Example
| Command> | db |
| Result> | db0:total_keys=802,string=402,list=100,set=100,zset=100,hash=100,module=0,stream=0,expires=2 |
Syntax
DB
- Available since Ent 8.1.0.
- Time complexity is O(1).
