In Elasticsearch, the data we index is stored in an index. The word index here is used as both a verb and a noun. Essentially, we perform an index operation in order to store data in an index. Before we can do this, however, we first need to understand the structure of an index and how to define one to meet specific requirements. In this hands-on lab, you will define Elasticsearch indexes by completing the following tasks: Configure the number of primary shards of an index Configure the number of replica shards of an index Allocate the shards for an index to hot nodes Allocate the shards for an index to warm nodes * Associate indexes with aliases

What are Hands-On Labs?

Hands-On Labs are scenario-based learning environments where learners can practice without consequences. Don't compromise a system or waste money on expensive downloads. Practice real-world skills without the real-world risk, no assembly required.
