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 5.0
To clear data of a DCS Redis 4.0 or 5.0 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.
- Currently, only DCS Redis 4.0 and 5.0 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 and run the FLUSHDB command on each master node.
- Redis Cluster data cannot be cleared by using Web CLI.
