Note that while the time complexity for this operation is O(n) the constant times are pretty low. For example Redis running on an entry level laptop can scan a 1 million keys database in 40 milliseconds. Still it's better to consider this one of the slow commands that may ruin the DB performance if not used with care.
In other words this command is intended only for debugging and special operations like creating a script to change the DB schema. Don't use it in your normal code. Use Redis Sets in order to group together a subset of objects.
Glob style patterns examples:
Use \ to escape special chars if you want to match them verbatim.
Time complexity: O(n) (with n being the number of keys in the DB, and assuming keys and pattern of limited length)

long seconds)
Volatile keys are stored on disk like the other keys, the timeout is persistent too like all the other aspects of the dataset. Saving a dataset containing expires and stopping the server does not stop the flow of time as Redis stores on disk the time when the key will no longer be available as Unix time, and not the remaining seconds.
Since Redis 2.1.3 you can update the value of the timeout of a key already having an expire
set. It is also possible to undo the expire at all turning the key into a normal key using the
PERSIST command.
Time complexity: O(1)
expire 在接口中 BinaryJedisCommandskey - seconds - public java.lang.Long expireAt(byte[] key,

EXPIRE but instead to get the number of
seconds representing the Time To Live of the key as a second argument (that is a relative way
of specifying the TTL), it takes an absolute one in the form of a UNIX timestamp (Number of
seconds elapsed since 1 Gen 1970).
EXPIREAT was introduced in order to implement the Append Only File persistence mode so that EXPIRE commands are automatically translated into EXPIREAT commands for the append only file. Of course EXPIREAT can also used by programmers that need a way to simply specify that a given key should expire at a given time in the future.
Since Redis 2.1.3 you can update the value of the timeout of a key already having an expire
set. It is also possible to undo the expire at all turning the key into a normal key using the

MSETNX will not perform any operation at all even if

Because of this semantic MSETNX can be used in order to set different keys representing different fields of an unique logic object in a way that ensures that either all the fields or none at all are set.
Both MSET and MSETNX are atomic operations. This means that for instance if the keys A and B are modified, another client talking to Redis can either see the changes to both A and B at once, or no modification at all.

For example LRANGE foobar 0 2 will return the first three elements of the list.
start and end can also be negative numbers indicating offsets from the end of the list. For example -1 is the last element of the list, -2 the penultimate element and so on.
Consistency with range functions in various programming languages
Note that if you have a list of numbers from 0 to 100, LRANGE 0 10 will return 11 elements, that is, rightmost item is included. This may or may not be consistent with behavior of range-related functions in your programming language of choice (think Ruby's Range.new, Array#slice or Python's range() function).
LRANGE behavior is consistent with one of Tcl.
Out-of-range indexes
Indexes out of range will not produce an error: if start is over the end of the list, or start > end, an empty list is returned. If end is over the end of the list Redis will threat it just like the last element of the list.
Time complexity: O(start+n) (with n being the length of the range and start being the start offset)
lrange 在接口中 BinaryJedisCommandskey - start - stop - public java.lang.String ltrim(byte[] key,
long start,
long stop)
For example LTRIM foobar 0 2 will modify the list stored at foobar key so that only the first three elements of the list will remain.
start and end can also be negative numbers indicating offsets from the end of the list. For example -1 is the last element of the list, -2 the penultimate element and so on.
Indexes out of range will not produce an error: if start is over the end of the list, or start > end, an empty list is left as value. If end over the end of the list Redis will threat it just like the last element of the list.
Hint: the obvious use of LTRIM is together with LPUSH/RPUSH. For example:
lpush("mylist", "someelement"); ltrim("mylist", 0, 99); *
The above two commands will push elements in the list taking care that the list will not grow without limits. This is very useful when using Redis to store logs for example. It is important to note that when used in this way LTRIM is an O(1) operation because in the average case just one element is removed from the tail of the list.
Time complexity: O(n) (with n being len of list - len of range)
ltrim 在接口中 BinaryJedisCommandskey - start - stop - public byte[] lindex(byte[] key,

If the value stored at key is not of list type an error is returned. If the index is out of range a 'nil' reply is returned.
Note that even if the average time complexity is O(n) asking for the first or the last element of the list is O(1).
Time complexity: O(n) (with n being the length of the list)
lindex 在接口中 BinaryJedisCommandskey - index - public java.lang.String lset(byte[] key,

Out of range indexes will generate an error.
Similarly to other list commands accepting indexes, the index can be negative to access elements starting from the end of the list. So -1 is the last element, -2 is the penultimate, and so forth.

blmove 在接口中 MultiKeyBinaryCommandssrcKey - dstKey - from - to - timeout - public java.util.List<byte[]> blpop(int timeout,
byte[]... keys)
The following is a description of the exact semantic. We describe BLPOP but the two commands are identical, the only difference is that BLPOP pops the element from the left (head) of the list, and BRPOP pops from the right (tail).
Non blocking behavior
When BLPOP is called, if at least one of the specified keys contain a non empty list, an element is popped from the head of the list and returned to the caller together with the name of the key (BLPOP returns a two elements array, the first element is the key, the second the popped value).
Keys are scanned from left to right, so for instance if you issue BLPOP list1 list2 list3 0 against a dataset where list1 does not exist but list2 and list3 contain non empty lists, BLPOP guarantees to return an element from the list stored at list2 (since it is the first non empty list starting from the left).
Blocking behavior
If none of the specified keys exist or contain non empty lists, BLPOP blocks until some other client performs a LPUSH or an RPUSH operation against one of the lists.
Once new data is present on one of the lists, the client finally returns with the name of the key unblocking it and the popped value.
When blocking, if a non-zero timeout is specified, the client will unblock returning a nil special value if the specified amount of seconds passed without a push operation against at least one of the specified keys.
The timeout argument is interpreted as an integer value. A timeout of zero means instead to block forever.
Multiple clients blocking for the same keys
Multiple clients can block for the same key. They are put into a queue, so the first to be served will be the one that started to wait earlier, in a first-blpopping first-served fashion.
blocking POP inside a MULTI/EXEC transaction
BLPOP and BRPOP can be used with pipelining (sending multiple commands and reading the replies in batch), but it does not make sense to use BLPOP or BRPOP inside a MULTI/EXEC block (a Redis transaction).
The behavior of BLPOP inside MULTI/EXEC when the list is empty is to return a multi-bulk nil reply, exactly what happens when the timeout is reached. If you like science fiction, think at it like if inside MULTI/EXEC the time will flow at infinite speed :)
Time complexity: O(1)

Multiple clients can block for the same key. They are put into a queue, so the first to be served will be the one that started to wait earlier, in a first-blpopping first-served fashion.
blocking POP inside a MULTI/EXEC transaction
BLPOP and BRPOP can be used with pipelining (sending multiple commands and reading the replies in batch), but it does not make sense to use BLPOP or BRPOP inside a MULTI/EXEC block (a Redis transaction).
The behavior of BLPOP inside MULTI/EXEC when the list is empty is to return a multi-bulk nil reply, exactly what happens when the timeout is reached. If you like science fiction, think at it like if inside MULTI/EXEC the time will flow at infinite speed :)
Time complexity: O(1)
brpop 在接口中 MultiKeyBinaryCommandstimeout - keys - When a non-zero timeout is specified, and the BLPOP operation timed out, the return value is a nil multi bulk reply. Most client values will return false or nil accordingly to the programming language used.

between the two commands.

used_memory is returned in bytes, and is the total number of bytes allocated by the program using malloc.
uptime_in_days is redundant since the uptime in seconds contains already the full uptime information, this field is only mainly present for humans.
changes_since_last_save does not refer to the number of key changes, but to the number of operations that produced some kind of change in the dataset.

MONITOR is a debugging command that outputs the whole sequence of commands received by the Redis server. is very handy in order to understand what is happening into the database. This command is used directly via telnet.
jedisMonitor - public java.lang.String slaveof(java.lang.String host,
int port)
The SLAVEOF command can change the replication settings of a slave on the fly. If a Redis server is already acting as slave, the command SLAVEOF NO ONE will turn off the replication turning the Redis server into a MASTER. In the proper form SLAVEOF hostname port will make the server a slave of the specific server listening at the specified hostname and port.
If a server is already a slave of some master, SLAVEOF hostname port will stop the replication against the old server and start the synchronization against the new one discarding the old dataset.
The form SLAVEOF no one will stop replication turning the server into a MASTER but will not discard the replication. So if the old master stop working it is possible to turn the slave into a master and set the application to use the new master in read/write. Later when the other Redis server will be fixed it can be configured in order to work as slave.

Saving a dataset containing expires and stopping the server does not stop the flow of time as Redis stores on disk the time when the key will no longer be available as Unix time, and not the remaining milliseconds.
Since Redis 2.1.3 you can update the value of the timeout of a key already having an expire
set. It is also possible to undo the expire at all turning the key into a normal key using the
PERSIST command.
