Atossa

Fast, polyglot database

Supported redis commands

Artimis doesn't implement all redis commandset. Instead, it supports the core concepts that will help you to build any type of data models on top of it.

✅ Not implemented yet
➕ Partially implemented
✔ Implemented

Connection

✅ ECHO message: Echo the given string
➕ PING [message]: Ping the server
✅ QUIT: Close the connection

Administrative

✔ COMMAND: Get array of supported commandset with details
✅ COMMAND COUNT: Get total number of supported commands
✅ COMMAND INFO command-name [command-name ...]: Get array of specific commands
✅ CONFIG: Returns current configuration of the server
✅ DBSIZE: Returns the number of keys in the selected database
➕ INFO: Get information and statistics about the server
✅ LOLWUT: WUT?!
✅ SHUTDOWN: Shut down the server
✅ TIME: Returns the current server time

Keys

✅ DEL key [key ...]: Delete a key
✅ EXISTS key [key ...]: Determine if a key exists
✅ EXPIRE key seconds: Set a key's TTL in seconds
✅ EXPIREAT key timestamp: Set the expiration for a key as a UNIX timestamp
➕ KEYS pattern
✅ PEXPIRE key milliseconds: Set a key's TTL in milliseconds
✅ PEXPIREAT key milliseconds-timestamp: Set the expiration for a keys as a UNIX timestamp specified in milliseconds
✅ PTTL key: Get the TTL for a key in milliseconds
✅ RANDOMKEY: Return a random key from the keyspace
✅ RENAME: Rename a key
✅ RENAMENX key newkey: Rename a key, only if the new key does not exists
✅ SORT key [BY pattern] [LIMIT offset count] [GET pattern [GET pattern ...]] [ASC|DESC] [ALPHA] [STORE destination]: Sort the elements in a list, set or sorted set
✅ TTL key: Get the time to live for a key
✅ TYPE key: Determine the type stored at the key

Strings

✅ APPEND key value: Append a value to a key
✅ DECR key: Decrement the integer value of a key by one
✅ DECRBY key decrement: Decrement the integer value of a key by the given number
✔ GET key: Get the value of a key
✅ GETRANGE key start end: Get a substring of the string stored at a key
✅ GETSET key value: Set the string value of a key and return its old value
✅ INCR key: Increment the integer value of a key by one
✅ INCRBY key increment: Increment the integer value of key by the given amount
✅ INCRBYFLOAT key increment: Increment the float value of a key by the given amount
✅ MGET key [key ...]: Get the values of all the given keys
✅ MSET key value [key value ...]: Set multiple keys to multiple values
✅ MSETNX key value [key value ...]: Set multiple keys to multiple values, only if none of the keys exist
✅ PSETEX key milliseconds value: Set the value and expiration in milliseconds of a key
➕ SET key value [EX seconds|PX milliseconds] [NX|XX] [KEEPTTL]: Set the string value of a key
✅ SETEX key value: Set the value and expiration of a key
✅ SETNX key value: Set the value of a key, only if a key does not exist
✅ SETRANGE key offset value: Overwrite part of a string at key starting at the specified offset
✅ STRLEN key: Get the length of the value stored in a key

Lists

✅ BLPOP key [key ...] timeout: Remove and get the first element in a list, or block until one is available
✅ BRPOP key [key ...] timeout: Remove and get the last element in a list, or block until one is available
✅ BRPOPLPUSH source destination timeout: Pop an element from a list, push it to another list and return it; or block until one is available
✔ LINDEX key index: Get an element from a list by its index
✅ LINSERT key BEFORE|AFTER pivot element: Insert an element before or after another element in a list
✔ LLEN key: Get the length of a list
✔ LPOP key: Remove and get the first element in a list
✔ LPUSH key element [element ...]: Prepend one or multiple elements to a list
✅ LPUSHX key element [element ...]: Prepend an element to a list, only if the list exists
✔ LRANGE key start stop: Get a range of elements from a list
✅ LREM key count element: Remove elements from a list
✔ LSET key index element: Set the value of an element in a list by its index
✅ LTRIM key start stop: Trim a list to the specified range
✔ RPOP key: Remove and get the last element in a list
✅ RPOPLPUSH source destination: Pop an element from a list, push it to another list and return it
✔ RPUSH key element [element ...]: Append one or multiple elements to a list
✅ RPUSHX key element [element ...]: Append an element to a list, only if the list exists

Incompatibility Notes

There is cases that this server behaviour is not compatible with Redis. You can find them listed below:

• Key must not be an empty string, if an empty key is provided server will return an ERR NILKEY Key is nil
