<div id="body1594694216151"><p id="css_02_0089__p147534195221">When creating an index for an Elasticsearch cluster, you can specify the number of shards, that is, the number of primary shards. Once an index is created, the number of primary shards cannot be changed, but the number of replicas can. <strong id="css_02_0089__b4153154310416">Number of replica shards = Number of primary shards x Number of replicas.</strong></p>
