Append a value to a key

O(1). The amortized time complexity is O(1) assuming the appended value is small and the already present value is of any size, since the dynamic string library used by Redis will double the free space available on every reallocation. If key already exists and is a string, this command appends the value at the end of the string. If key does not exist it is created and set as an empty string, so APPEND will be similar to SET in this special case.

Authenticate to the server

Request for authentication in a password protected Redis server. Redis can be instructed to require a password before allowing clients to execute commands. This is done using the requirepass directive in the configuration file. If password matches the password in the configuration file, the server replies with the OK status code and starts accepting commands. Otherwise, an error is returned and the clients needs to try a new password. Note: because of the high performance nature of Redis, it is possible to try a lot of passwords in parallel in very short time, so make sure to generate a strong and very long password so that this attack is infeasible.

Asynchronously rewrite the append-only file

Rewrites the append-only file to reflect the current dataset in memory. If BGREWRITEAOF fails, no data gets lost as the old AOF will be untouched.

Asynchronously save the dataset to disk

Save the DB in background. The OK code is immediately returned. Redis forks, the parent continues to server the clients, the child saves the DB on disk then exit. A client my be able to check if the operation succeeded using the LASTSAVE command.
