Verifying High Availability
You can verify the health and status of your cluster using the _cluster/health endpoint:
GET /_cluster/health?pretty
The output should show a green status, indicating that all primary and replica shards are allocated.
High Availability and Disaster Recovery Strategies for Elasticsearch
Elasticsearch is a powerful distributed search and analytics engine, but to ensure its reliability in production, it’s crucial to implement high availability (HA) and disaster recovery (DR) strategies. These strategies help maintain service continuity and protect data integrity in the face of failures or disasters.
This article will guide you through the key concepts, strategies, and best practices for achieving high availability and disaster recovery in Elasticsearch, with detailed examples and outputs.
