How to manage counters?
We can mange the Redis counters using different commands and by using those commands you are able to increment and decrement numeric values.
By using INCR and DECR commands:
Redis provides two simple commands, INCR and DECR, to increment and decrement a numeric value stored in a key.
Example:
SET user:id dozen 12
INCR dozen
GET dozen
Output: 13
By using SET command using NX:
This command is used for initialization of the strings basically.
By using INCRBYFLOAT:
This command is used to increment the floating values.
SET counter= 3.6
INCRBYFLOAT counter 2.5
GET counterOutput: 6.1
