Redis Training in Hyderabad with Hands On

Redis 

Redis is an open source (BSD licensed), in-memory data structure store, used as database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps,hyperloglogs and geospatial indexes with radius queries. Redis has built-in replication, Lua scripting, LRU eviction,transactions and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.Redis Training Hyderabad.

You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing an element to a list; computing set intersection, union and difference; or getting the member with highest ranking in a sorted set.

In order to achieve its outstanding performance, Redis works with an in-memory dataset. Depending on your use case, you can persist it either by dumping the dataset to disk every once in a while, or by appending each command to a log. Persistence can be optionally disabled, if you just need a feature-rich, networked, in-memory cache.

Redis also supports trivial-to-setup master-slave asynchronous replication, with very fast non-blocking first synchronization, auto-reconnection with partial resynchronization on net split.

Other features include:

  • Transactions

  • Pub/Sub

  • Lua scripting

  • Keys with a limited time-to-live

  • LRU eviction of keys

  • Automatic failover

You can use Redis from most programming languages out there.

What Is In-Memory, Key-Value Store

Key-Value store is a storage system where data is stored in form of key and value pairs. When we say in-memory key-value store, by that we mean that the key-value pairs are stored in primary memory(RAM). So we can say that Redis stored data in RAM in form of key-value pairs.

In Redis, key has to be a string but value can be a string, list, set, sorted set or hash.

These are some example of Redis key-values pairs

                                 name=”narayan”
                                 profession=["web", "mobile"]  

Here name and profession are keys. And we have their respective values on right.

Advantage And Disadvantage of Redis over DBMS

Database Management systems store everything in second storage which makes read and write operations very slow. But Redis stores everything in primary memory which is very fast in read and write of data.

Primary memory is limited(much lesser size and expensive than secondary) therefore Redis cannot store large files or binary data. It can only store those small textual information which needs to be accessed, modified and inserted at a very fast rate. If we try to write more data than available memory then we will receive errors. 

 

Redis Replication

Replication is a technique involving many computers to enable fault-tolerance and data accessibility. In a replication environment many computers share the same data with each other so that even if few computers go down, all the data will be available.
