SpatialSparkApp

Introduction

This repository will be used as a codebase for our efforts to realize spatio-temporal queries on top of Spark-Streaming.

Requirements

You need to have sbt 0.13x installed. More information about [sbt] (http://www.scala-sbt.org/0.13/tutorial/Setup.html)

Building

To build a single jar for Spark cluster submission.

$ sbt assembly

Eclipse integration

You need ScalaIDE Eclipse plugin.

The project template is configured with the eclipse project generator plug-in so that Eclipse can be used as an IDE. To generate the required files for Eclipse, run:

$ sbt eclipse

Then, do File -> Import ... -> Existing Projects into workspace

Notes

If the dependencies change, you need to run again:

$ sbt eclipse

and refresh your project directory from the Project Explorer.

Kafka as Source and Sink for Queries

If you want to mimic a full stream processing cycle, where you have the following pipleline:

Input streams --> Processing --> Output streams

Instead of the following:

Input streams --> Processing --> Output Console

You can use Kafka as a source and as a sink. The example application is at

queries.Kafka

Obviously, you need Kafka deployed. Check out their website http://kafka.apache.org/.
