Introduction to Redis

Redis is an open source (BSD licensed), 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.

Defining profile

Nexial simplifies the connectivity to a Redis server via the concept of a profile, much like the case for rdbms, ssh and `aws.s3 . In this case, the profile would contain the connection URL to the target Redis server. For example,

Here, myredis would be considered the profile name, and be used as the profile argument in commands below.

Note: Future version of Nexial might include additional Redis connectivity details.
