Maxwell’s Daemon (maxwells-daemon.io) an application that reads MySQL binlogs and writes row updates as JSON to Kafka, Kinesis, or other streaming platforms. Maxwell has low operational overhead, requiring nothing but mysql and a place to write to. Its common use cases include ETL, cache building/expiring, metrics collection, search indexing and inter-service communication. Maxwell gives you some of the benefits of event sourcing without having to re-architect your entire platform. Maxwell (github)
