The Redis Evict block removes old or unused data from the cache to free up memory and ensure that old data is not retrieved. This is useful when cached data becomes outdated due to updates or changes in the underlying data source and helps free up memory.

To evict data from the Redis cache, identify the cache key that stores the data to be removed. Then, configure the Redis Evict block by specifying this key to target the correct data. Finally, execute the Redis Evict block to remove the data from the cache, to ensure future requests fetch the latest information.
