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
