Configure Shard Allocation and Forced Awareness in Elasticsearch
BigData Training Architect II in Content
With Elasticsearch, you have the potential to scale your cluster to be highly available. To ensure your data survives a full zone or rack failure, you can spread your data across multiple zones and use shard allocation awareness to ensure that all replica shards are allocated to a different zone than that of their primary shard. This allows another level of fault tolerance beyond just node failure. In this hands-on lab, you are given the opportunity to exercise the following: Apply node attributes to each data node in a cluster. Configure shard allocation awareness for a cluster in multiple zones. * Test shard allocation awareness behavior by stopping all nodes in a zone.
