1. Norikra v1.0.0: Schema-less Stream Processing with SQL

    I’ve just released Norikra v1.0.0, which is a server software to provide schema-less stream processing with SQL.

    I believe that this is the first software which realize user-friendly stream processing. In fact, we can deploy norikra server in 3 minutes! (How long we must struggle for the first test program on Storm?)

    We can send any events (key-value pairs, can be nested deeply) to Norikra server, and can execute SELECT queries for these events like standard SQL.

    query example

    Any programmings on frameworks are not required. We should only write SQL and register it (on WebUI, over RPC or by CLI). And then, send input events into norikra server. And we can add/remove queries anytime.

    Norikra supports complex events which have nested lists and key-value pairs, which is accessed on SQL directly, without any schema definitions.

    And Norikra v1.0.0 supports many more features what you wants! (User-defined functions, JOINs and subqueries, loopback query group, …)

    We are already using norikra on our production environment. Please try it on your workload, and let me know about missing features, performances or how you enjoyed stream processing!
