Hi all,
You may have seen a repo in our Github organization called job-scheduler. The Open Distro for Elasticsearch Job Scheduler provides an extendable framework for Elasticsearch plugin developers to run custom jobs on Elasticsearch. For example, you might want to write a plugin which runs an aggregation query against raw data and save the aggregated data into a new index every hour, or you might want to write a plugin which periodically polls metrics in Elasticsearch and posts the results to a Webhook.
The inspiration of the Job Scheduler plugin came from building our Alerting plugin. During the development effort to build scheduled monitors and triggers, we realized that we could build a framework to make it easy for other Elasticsearch plugins to be able to schedule and manage jobs.
The Job Scheduler is currently under development in our dev branch. Feel free to check it our and extend our example plugin.
