How to clear redis cache in aws?

Run the FLUSHDB command to clear the data in the currently selected DB. Data of a DCS Redis 4.0 or 5.0 instance can be cleared all at once on the console or by the FLUSHDB or FLUSHALL command in redis-cli. To clear data of a Redis Cluster instance, run the FLUSHDB or FLUSHALL command on every shard of the instance.
