norikra-1's Introduction

Norikra

Norikra is an open-source Stream Processing Server with SQL.

  • Schema-less event streams (called as 'target')
  • SQL processing with window specifier supports, and JOINs, SubQueries
  • Complex input/output events with nested Hashes and Arrays, and Query supports
  • Dynamic query registration/removing, without any restarts
  • Ultra fast bootstrap and small start
  • UDF plugins

Install and Execute

On JRuby environment, do these command (and, that all):

gem install norikra

To execute:

norikra start

For JRuby installation, you can use rbenv, rvm and xbuild, or install JRuby directly.

Install and launch

How to execute norikra server and tests in development

Fix code and tests:

  1. clone this repository
  2. run bundle install w/ jruby
  3. add/fix spec in spec/*_spec.rb
  4. fix code in lib
  5. run bundle exec rake

Run tests faster than 2 or more times:

  1. execute spork
  2. execute script/spec_server_pry in another terminal
  3. run rspec in pry console (executed fastly after second times)

Execute norikra server with target/query continuation:

  1. bundle exec rake devserver
  2. Ctrl-C and re-execute for updated code
