Methods
Create a cluster object.
Compress data with Relay's currently configured compression algorithm.
Returns the number of milliseoconds since Relay has received a reply from the cluster.
Returns an array of endpoints along with each of their keys cached in runtime memory.
Return a list of master nodes
Returns the serialized and compressed value.
Returns the value with the prefix.
Returns the serialized value.
Uncompress data with Relay's currently configured compression algorithm.
Returns the unserialized and decompressed value.
Returns the unserialized value.
Interact with Redis' ACLs
Adds allow pattern(s). Only matching keys will be cached in memory.
Adds ignore pattern(s). Matching keys will not be cached in memory.
If key already exists and is a string, this command appends the value at the end of the string. If key does not exist it is created and set as an empty string, so APPEND will be similar to SET in this special case.
Asynchronously rewrite the append-only file.
Paus the client until sufficient local and/or remote AOF data has been flushed to disk.
Asynchronously save the dataset to disk.
Count the number of set bits (population counting) in a string.
Perform a bitwise operation on one or more keys, storing the result in a new key.
Return the position of the first bit set to 1 or 0 in a string.
BLMOVE is the blocking variant of LMOVE. When source contains elements, this command behaves exactly like LMOVE. When used inside a MULTI/EXEC block, this command behaves exactly like LMOVE.
Pop elements from a list, or block until one is available
BLPOP is a blocking list pop primitive. It is the blocking version of LPOP because it blocks the connection when there are no elements to pop from any of the given lists.
BRPOP is a blocking list pop primitive. It is the blocking version of RPOP because it blocks the connection when there are no elements to pop from any of the given lists.
Atomically returns and removes the last element (tail) of the list stored at source, and pushes the element at the first element (head) of the list stored at destination.
Remove and return members with scores in a sorted set or block until one is available
BZPOPMAX is the blocking variant of the sorted set ZPOPMAX primitive.
BZPOPMIN is the blocking variant of the sorted set ZPOPMIN primitive.
