The author describes their motivation to bring Redis modules into ARM land, specifically targeting IoT devices. They introduce RedisEdge, an aggregate of three Redis modules (RedisGears, RedisAI, and RedisTimeSeries), which can be run as a Docker image. The author explains that they will take each component of RedisEdge (RedisTimeSeries, RedisGears, and RedisAI) and describe how to port them to ARM platforms using various build methods, including automating the process for each component. They emphasize the importance of testing on physical ARM devices rather than virtualized/emulated/containerized tests and recommend using a Raspberry Pi 4 with Raspbian or Ubuntu as the target device. The author also outlines the steps needed to set up a network connection between the Raspberry Pi and a workstation, including setting up NFS for sharing files between the two.
