Before 2.15.0, Kvrocks only allowed using [the namespace feature](https://kvrocks.apache.org/docs/namespace) to isolate your data. That said, the `SELECT` command is just a placeholder and does not switch between databases. And now, the Redis database mechanism is supported, and you can enable it by setting the `redis-database` to the database number you expect in the configuration file. To be noticed, we don't allow using the namespace feature and the Redis database at the same time. ::: ### COMMAND subcommands These commands are subcommands for `COMMAND`, using as `COMMAND COUNT` etc. | SUBCOMMAND | Supported OR Not | Since Version | Description | | ---------- | ---------------- | ------------- | ------------------------------------------------------------------------------------------------------------- | | COUNT | ✓ | v2.0.1 | Returns a count of commands. | | GETKEYS | ✓ | v2.0.1 | Extracts the key names from an arbitrary command. | | INFO | ✓ | v2.0.1 | Returns information about one, multiple or all commands. | ### CONFIG subcommands These commands are subcommands for `CONFIG`, using as `CONFIG GET` etc. | SUBCOMMAND | Supported OR Not | Since Version | Description | | ---------- | ---------------- | ------------- | ------------------------------------------------------------------------------------------------------------- | | GET | ✓ | v1.0.0 | Returns the effective values of configuration parameters. | | SET | ✓ | v1.0.0 | Sets configuration parameters in-flight. | | REWRITE | ✓ | v1.0.0 | Persists the effective configuration to the file. | | RESETSTAT | x | - | Resets the server's statistics. | ### NAMESPACE subcommands These commands are subcommands for `NAMESPACE`, using as `NAMESPACE GET` etc. | SUBCOMMAND | Supported OR Not | Since Version | Description | | ---------- | ---------------- | ------------- | ------------------------------------------- | | GET | ✓ | v1.0.0 | Retrieve information of namespaces. | | SET | ✓ | v1.0.0 | Set the password of a namespace. | | ADD | ✓ | v1.0.0 | Add a new namespace. | | DEL | ✓ | v1.0.0 | Deletes a namespace. | | CURRENT | ✓ | v2.14.0 | Returns the current namespace name. | ### CLIENT subcommands These commands are subcommands for `CLIENT`, using as `CLIENT INFO` etc. | SUBCOMMAND | Supported OR Not | Since Version | Description | | ------------ | ---------------- | ------------- | ------------------------------------------------------------------------------------------------------------- | | CACHING | x | - | Instructs the server whether to track the keys in the next request. | | GETNAME | ✓ | v1.0.0 | Returns the name of the connection. | | GETREDIR | x | - | Returns the client ID to which the connection's tracking notifications are redirected. | | ID | ✓ | v1.0.0 | Returns the unique client ID of the connection. | | INFO | ✓ | v2.4.0 | Returns information about the connection. | | KILL | ✓ | v1.0.0 | Terminates open connections. | | LIST | ✓ | v1.0.0 | List open connections. | | NO-EVICT | x | - | Set the client eviction mode of the connection. | | NO-TOUCH | x | - | Controls whether commands sent by the client affect the LRU/LFU of the accessed keys. | | PAUSE | ✓ | unstable | Suspends commands processing. | | REPLY | ✓ | v2.13.0 | Instructs the server whether to reply to commands. | | SETINFO | ✓ | unstable | Sets information specific to the client or connection. | | SETNAME | ✓ | v1.0.0 | Sets the connection name. | | TRACKING | x | - | Controls server-assisted client-side caching for the connection. | | TRACKINGINFO | x | - | Returns information about the server-assisted client-side caching for the connection. | | UNBLOCK | x | - | Unblocks a client blocked by a blocking command from a different connection. | | UNPAUSE | ✓ | unstable | Resumes processing commands from paused clients. | ### SLOWLOG subcommands These commands are subcommands for `SLOWLOG`, using as `SLOWLOG GET` etc. | SUBCOMMAND | Supported OR Not | Since Version | Description | | ---------- | ---------------- | ------------- | ------------------------------------------------------------------------------------------------------------- | | GET | ✓ | v1.0.0 | Returns the slow log's entries. | | LEN | ✓ | v1.0.0 | Returns the number of entries in the slow log. | | RESET | ✓ | v1.0.0 | Clears all entries from the slow log. | ##
