List keys
Usage: ELS *
Output is key_name. Example) key1
📍Output (query) count limit: limited by redis.conf ll_max 10000.
📍Why the limit: if there are very many keys (e.g. 10 million or more) and there is no limit,
other commands cannot run while this command runs, which can be a problem on production servers.
The default ll_max is 10000. You can change it at runtime with CONFIG SET if needed.
Example
| Command> | els ℹ️ If you do not specify 'key_pattern', all keys are listed. |
| Result> | 0) key |
| 1) keyB_000652109500 | |
| 2) keyB_000652109500 | |
| ....................... | |
| 804) myhash76 | |
| Command> | els * |
| Result> | 0) key |
| 1) keyB_000652109500 | |
| 2) keyB_000652109500 | |
| ....................... | |
| 804) myhash76 | |
| Command> | els keyA* ℹ️ List keys starting with keyA |
| Result> | 0) key |
| 1) keyA_000375248904 | |
| 2) keyA_000082855540 | |
| ....................... | |
| 200) keyA_000962842702 | |
| Command> | els * string ℹ️ List string data type keys |
| Result> | 0) key |
| 1) keyB_000538223312 | |
| 2) keyB_000652109500 | |
| ....................... | |
| 403) keyA_000962842702 ℹ️ From ent810, data is stored separately by data type, so specifying a data type is recommended. | |
| Command> | els * string count 10 ℹ️ Specify the output (query) count |
| Result> | 0) key |
| 1) keyB_000538223312 | |
