[druid-user] Druid self help documentation

Hi All,

For training purpose i had created content on RDBMS, OLAP and Apache Druid.

The entire content is available @

The purpose of the material is to understand OLAP concepts, inner workings of Druid (w.r.t segment layout). The repository also has a set of ingestion specs with - filter, transformation, javascript with sample data. The deck slides also cover HLL, Thetasketch.

Hope it will be useful to the druid community. If you have any comments/feedback, feel free to drop a mail to me.

Regards, Chari.

This is very comprehensive and extremely helpful. Thank you so much for putting the time and hard work into this.

That’s awesome!!
