How do I delete everything in Redis?

I want to delete all keys. I want everything wiped out and give me a blank database.

Is there a way to do this in Redis client?

If you are using Java then from the documentation, you can use any one of them based on your use case.

/**
 * Remove all keys from all databases.
 *
 * @return String simple-string-reply
 */
String flushall();

/**
 * Remove all keys asynchronously from all databases.
 *
 * @return String simple-string-reply
 */
String flushallAsync();

/**
 * Remove all keys from the current database.
 *
 * @return String simple-string-reply
 */
String flushdb();

/**
 * Remove all keys asynchronously from the current database.
 *
 * @return String simple-string-reply
 */
String flushdbAsync();

Code:

RedisAdvancedClusterCommands syncCommands = // get sync() or async() commands 
syncCommands.flushdb();
