Redis and Redis Sentinel Crash Course - Redis Commands and High Availability tutorial

In This tutorial we will talk about Redis and Sentinel high availability. you will have it in 2 parts. Part 1 will all theoretical and the second will have our hands dirty with the code :D have fun!. Github repository: https://github.com/bloodymind/redis-m... Part 1 00:52: What is Redis? 01:42: Redis use cases 02:02: Who using Redis in Production? 02:50: Redis Sentinel Part 2 04:25: Redis Installation 09:30: Redis Important Comands / Strings INFO: Return informations and statistics about the server in a format that is simple to parse by computers and easy to read by humans KEYS: Returns all keys matching pattern SET: Add/update a record GET: Gets a single record EXISTS: Returns if a record exists or not (0 or 1) EXPIRE: Set a timeout on a key. After the timeout has expired, the key will automatically be deleted TTL: Returns the remaining time to live of a key that has a timeout SETEX: Equivalent to executing SET and EXPIRE SETNX: Set a single record if not exists INCR: Increment a number by 1 INCRBY: Increment by a different number DECR: Decrement by 1 DECRBY: Decrement by a different number APPEND: Appends the value at the end of a string MGET: Gets multiple records MSET: Sets multiple record DEL: Delete one or multiple records 19:15: Redis Important Comands / Hashes HSET: Sets field in the hash stored at key to value HGET: Returns the value associated with field in the hash stored at key. HMGET: Returns the multiple values associated with field in the hash stored at key. HMSET: Sets multiple values associated with field in the hash stored at key. HGETALL: Returns all fields and values of the hash stored at key HINCRBY: Increment by a different number HDECRBY: Decrement by a different number 24:05: Redis Important Comands / Sets SADD: Add the specified members to the set stored at key. Specified members that are already a member of this set are ignored SMEMBERS: Returns all the members of the set SCARD: Returns the set cardinality (number of elements) SISMEMBER: Returns if member is a member of the set stored at key. SREM: Remove the specified members from the set stored at key 25:58: Redis Important Comands / Sorted Sets ZADD: Adds specified members with the specified scores to the sorted set ZRANGE: Returns the specified range of elements in the sorted set stored at key. The elements are considered to be ordered from the lowest to the highest score ZREM: Removes the specified members from the sorted set stored at key. Non existing members are ignored. ZSCORE: Returns the score of member in the sorted set at key. 27:54: Redis Important Comands / Pub-Sub PUBLISH: Posts a message to the given channel. SUBSCRIBE: Subscribes the client to the specified channels. 30:06: Redis Important Comands / Transactions MULTI: Marks the start of a transaction block. Subsequent commands will be queued for atomic execution using EXEC. EXEC: Executes all previously queued commands in a transaction. DISCARD: Flushes all previously queued commands in a transaction. 31:50: Redis Important Comands / Connection AUTH: Request for authentication in a password-protected Redis server. PING: used to test if a connection is still alive, or to measure latency. Returns PONG if no argument is provided, otherwise return a copy of the argument as a bulk. SELECT: Selectable Redis databases are a form of namespacing. 34:46: Slave Master configuration 39:49: Sentinel Configuration and Failover test
