Streaming Data in Elasticsearch 7.13
In previous versions of Elasticsearch, you had to use a series of APIs to continuously stream data to a “hot” index alias and roll that alias over to new indices as they filled up. Now, in recent versions of Elasticsearch, we can leverage data streams to handle this operation for us. In this hands-on lab, you will create data streams for time-series data in Elasticsearch so that we can continuously write data to indices that automatically rollover when they reach a specified size or age.
