Name : redis
Version : 5.0.3
Release : 1.module_el8.0.0+6+ab019c03

Summary : A persistent key-value database
URL : http://redis.io
License : BSD and MIT
Description : Redis is an advanced key-value store. It is often referred to as a data
: structure server since keys can contain strings, hashes, lists, sets and
: sorted sets.
:
: You can run atomic operations on these types, like appending to a string;
: incrementing the value in a hash; pushing 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.
:
: Redis also supports trivial-to-setup master-slave replication, with very
: fast non-blocking first synchronization, auto-reconnection on net split
: and so forth.
:
: Other features include Transactions, Pub/Sub, Lua scripting, Keys with a
: limited time-to-live, and configuration settings to make Redis behave like
: a cache.
:
: You can use Redis from most programming languages also.
