Syntax
INCRBY key increment
Time complexity: O(1)
Increments the number stored at key
by increment
.
If the key does not exist, it is set to 0
before performing the operation.
An error is returned if the key contains a value of the wrong type or contains a
string that can not be represented as integer.
This operation is limited to 64 bit signed integers.
See INCR
for extra information on increment/decrement operations.
Return
Integer reply: the value of key
after the increment
Examples
dragonfly> SET mykey "10"
"OK"
dragonfly> INCRBY mykey 5
