Summary

In this chapter, we learned a few things about Elasticsearch such as the node discovery, what this module is responsible for, and how to tune it. We also looked at the recovery and gateway modules, how to set them up to match our cluster, and what configuration options they provide. We also discussed some of the Elasticsearch internals, and we used these to tune our cluster for high indexing and high querying use cases. And finally, we've used templates and dynamic mappings to help us manage our dynamic indices better.

In the next chapter, we'll focus on some of the Elasticsearch administration capabilities. We will learn how to back up our cluster data and how to monitor our cluster using the available API calls. We will discuss how to control shard allocation and how to move shards around the cluster, again using the Elasticsearch API. We'll learn what index warmers are and how they can help us, and we will use aliases. Finally, we'll learn how to install and manage Elasticsearch...
