Elasticsearch (elasticsearch)

Elasticsearch is a distributed, RESTful search and analytics engine capable of addressing a growing number of use cases. As the heart of the Elastic Stack, it centrally stores your data so you can discover the expected and uncover the unexpected. See https://www.elastic.co/products/elasticsearch

Testing Elasticsearch with docker and Java High Level REST Client

Use Elasticsearch cat nodes API to understand the state of your Elasticsearch: id, name, IP address, CPU, load, memory, and much more.

Elasticsearch Scroll API sample written in Java, useful for retrieving large numbers of results (or even all results) from a single search request.

Initializing Elasticsearch client, sending a single index request or a bulk index request, index response, different content types, refresh policy etc.

Writing unit tests for Elasticsearch using Elasticsearch Single Node Test Case (ESSingleNodeTestCase), a derived class of ESTestCase which simplifies the testing set up for you.
