HINCRBY key field increment
Available since: 2.0.0
Time complexity: O(1)
ACL categories:
@write
@hash
@fast
Increments the number stored at field in the hash stored at key by
increment.
If key does not exist, a new key holding a hash is created.
If field does not exist the value is set to 0 before the operation is
performed.
The range of values supported by HINCRBY is limited to 64 bit signed integers.
Return
Integer reply: the value at field after the increment operation.
Examples
Since the increment argument is signed, both increment and decrement
operations can be performed:
