Method Detail

configGet

List<String> configGet(String pattern)

Used to read the configuration parameters of Redis server.

Parameters:

pattern - name of Redis server's configuration

Returns:

config value of Redis server

configGet

List<String> configGet(String... patterns)

Used to read the configuration parameters of Redis server.

Parameters:

patterns - names of Redis server's configuration

Returns:

values of Redis server's configuration

configGet

List<byte[]> configGet(byte[] pattern)

Used to read the configuration parameters of Redis server.

Parameters:

pattern - name of Redis server's configuration

Returns:

value of Redis server's configuration

configGet

List<byte[]> configGet(byte[]... patterns)

Used to read the configuration parameters of Redis server.

Parameters:

patterns - names of Redis server's configuration

Returns:

values of Redis server's configuration

configSet

String configSet(String parameter,
                 String value)

Used in order to reconfigure the Redis server at run time without the need to restart.

Parameters:

parameter - name of Redis server's configuration

value - value of Redis server's configuration

Returns:

OK when the configuration was set properly. Otherwise, an error is returned.

configSet

String configSet(String... parameterValues)

configSet

String configSet(byte[] parameter,
                 byte[] value)

Used in order to reconfigure the Redis server at run time without the need to restart.

Parameters:

parameter - name of Redis server's configuration

value - value of Redis server's configuration

Returns:

OK when the configuration was set properly. Otherwise, an error is returned.

configSet

String configSet(byte[]... parameterValues)

configResetStat

String configResetStat()

Resets the statistics reported by Redis using the INFO command.

These are the counters that are reset:

1) Keyspace hits 2) Keyspace misses 3) Number of commands processed 4) Number of connections received 5) Number of expired keys 6) Number of rejected connections 7) Latest fork(2) time 8) The aof_delayed_fsync counter

Returns:

always OK.

configRewrite

String configRewrite()

Rewrites the redis.conf file the server was started with, applying the minimal changes needed to make it reflect the configuration currently used by the server, which may be different compared to the original one because of the use of the CONFIG SET command.

Returns:

OK when the configuration was rewritten properly. Otherwise, an error is returned.
