How Do I Clear Redis Data?
Exercise caution when clearing data.
- Redis 4.0 or later
To clear data of a DCS Redis 4.0 or later instance, you can run the FLUSHDB or FLUSHALL command in redis-cli, use the data clearing function on the DCS console, or run the FLUSHDB command on Web CLI.
To clear data of a Redis Cluster instance, run the FLUSHDB or FLUSHALL command on every shard of the instance. Otherwise, data may not be completely cleared.
- When you run the FLUSHDB command on Web CLI, only one shard is cleared at a time. If there are multiple shards, connect to the master node of each shard and run the FLUSHDB command separately.
- Redis Cluster data cannot be cleared by using Web CLI.
