How Do I Clear Redis Data?¶
Exercise caution when clearing data.
Redis 3.0
Data of a DCS Redis 3.0 instance cannot be cleared on the console, and can only be cleared by the FLUSHDB or FLUSHALL command in redis-cli.
Run the FLUSHALL command to clear all the data in the instance.
Run the FLUSHDB command to clear the data in the currently selected DB.
Redis 4.0 and later
To clear data of a DCS Redis 4.0 and 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.
Note
Currently, only DCS Redis 4.0 and later instances support data clearing by using the DCS console and by running the FLUSHDB command on Web CLI.
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.
