I am using Redis cluster version redis-5.0.5. I want to see all the keys present in my Redis cluster. I know for standalone we use KEYS * to get all the keys.
what is the way to see all keys in Redis cluster?
$ redis-cli -h hostname -p 90001 -c
hostname:90001> KEYS *
(empty list or set)
// I have data on my cluster
411
To list the keys in the Redis data store, use the KEYS command followed by a specific pattern. Redis will search the keys for all the keys matching the specified pattern. In our example, we can use an asterisk (*) to match all the keys in the data store to get all the keys.
Open the Command Prompt and change to the Redis directory and run the command c:\Redis>redis-cli -h Redis_Cluster_Endpoint -p 6379 . Run Redis commands. You are now connected to the cluster and can run Redis commands like the following.
A Redis server has 16 databases by default. You can check the actual number by running redis-cli config get databases. In interactive mode, the database number is displayed in the prompt within square braces. For example, 127.0. 0.1:6379[13] shows that the 13th database is in use.
The Redis KEYS command returns all the keys in the database that match a pattern (or all the keys in the key space). Similar commands for fetching all the fields stored in a hash is HGETALL and for all fetching the members of a SMEMBERS. The keys in Redis themselves are stored in a dictionary (aka a hash table).
Basically, you'd need to run KEYS * (not in production, please!) on every one of the nodes. The cli can do this with the '--cluster call' command, like so:
redis-cli --cluster call hostname:90001 KEYS "*"
