RedisEdge is Redis packaged for IoT/IIoT edge computing solutions
Redis is an in-memory data structure store, used as a 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.
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 HA asynchronous replication, with very fast non-blocking first synchronization, auto-reconnection with partial resynchronization on net split.
Redis is written in ANSI C and works in most POSIX systems.
Redis requires less than 5MB of memory and runs without compromise on small ARM32 based devices and up.
