Apache Kylin: OLAP Cubes for NoSQL Data Stores

Ted Dunning View Bio

April 16, 2015 - 12:40-13:20

The Apache Kylin project emerged from an EBay internal effort to build efficient OLAP capabilities without support from the indexes available in a relational store. Instead, Kylin stores cube summaries in a NoSQL database and depends on the advanced query optimizers available from Apache Calcite to allow query reformulation as needed.

I will describe how Kylin does what it does and also what the implications are for other Hadoop eco-systems that use Calcite optimizers such as Apache Drill and possibly even Apache Hive.

This project has implications beyond Hadoop, however, since the flexible nature of Apache Kylin (especially augmented by Drill), allow SQL with OLAP cube capability on almost any NoSQL store.

How (the Internet of) Things are Turning the Internet Upside Down

Ted Dunning View Bio

April 16, 2015 - 15:35-16:15

Just when we thought the last mile problem was solved, the Internet of Things is turning the last mile problem of the consumer internet into the first mile problem of the industrial internet. This inversion impacts every aspect of the design of networked applications. I will show how to use existing Hadoop ecosystem tools, such as Spark, Drill and others, to deal successfully with this inversion.
