Calculating Shard Count for OpenSearch Clusters

An important component of OpenSearch cluster optimization is assigning the proper number of shards to your cluster. OpenSearch shards enable parallelization of data processing across both a single node and multiple nodes.

In the article linked below we walk through the structure of an OpenSearch cluster and explain how to calculate the optimal number of shards for your cluster.

Keep in mind there can always be exceptions to any rule. And we talk through one of those scenarios as well.
