Redis String: INCRBY

Redis INCRBY Command

Redis INCRBY command is used to increment the number stored at key by specified value. 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 an integer.

Here are some common uses and scenarios for the "INCRBY" command:

• Incremental Counting: Increment integers by a specified value (e.g., for counting).
• Batch Processing: Increase values of multiple keys by specified amounts efficiently.
• Rate Limiting: Track and enforce rate limits by incrementing values in controlled increments.
• Atomic Operations: Ensure atomicity when incrementing values in a multi-client environment.
• Data Aggregation: Aggregate data by adding values together for reporting or analysis.
