Example End-to-End Data Pipeline with Apache Spark from Data Analysis to Data Product

Scenario

As an e-commerce company, we would like to recommend products that users may like in order to increase sales and profit.

Notebooks / Source Code

The notebooks are accessible at http://brkyvz.github.io/spark-pipeline.

Right now, only Scala examples are available.

Procedure

This example pipeline shows steps on how to start with analyzing your data, training a machine learning model, and then monitoring the health of your web service using Spark.

• Step 1: We will first start out by analyzing our data. If you don't have a dataset readily available, feel free to use the movielens dataset provided with Spark. You may use the code available under step-0/movielens.scala for this purpose.

• Step 2: We will train a recommender system using Spark ML's ALS algorithm. We will use cross-validation to pick the best hyper-parameters and then make predictions on a test dataset. The model then can be exported to a database, such as Cassandra, for interactive querying through a Web Service.

• Step 3: We will monitor the response times of our web services using Spark Streaming and send notifications when we come across an anomalous web service.
