In the previous chapter, we covered an overview of Apache Hadoop and its various components. We also presented an overview of Storm-YARN, and looked at deploying Storm-YARN on Apache Hadoop.
In this chapter, we will explain how you can integrate Storm with other databases for storing the data, and how we can use Esper inside a Storm bolt to support the windowing operation.
The following are the key points we are going to cover in this chapter:
- Integration of Storm with HBase
- Integration of Storm with Redis
- Integration of Storm with Elasticsearch
- Integration of Storm with Esper to perform the windowing operation
