In this section, you will be looking into some hot topics, such as machine learning and Apache Spark support with Elasticsearch. You will also be shown how to solve a text classification problem by using Elasticsearch and scikit-learn. You will also learn how to read data from an Elasticsearch index, perform some computations using Spark, and then write the results to another Elasticsearch index. And, at the end of the section, you will need to put most of what you learned in the previous chapters together to build the final project, that is, building Analytics RESTful Services.
This section is comprised the following chapters:
- Chapter 16, Machine Learning with Elasticsearch
- Chapter 17, Spark and Elasticsearch for Real-time Analytics
- Chapter 18, Building Analytics RESTful Services
