Useful Elasticsearch API Calls

, Solutions Architect, outlines how to manage Elasticsearch (Elastic) clusters and indices which are crucial for maintaining a Quantexa implementation. This article provides an overview of common Elasticsearch API calls that can be used for cluster and index management. 

Key topics:

1. Cluster Management:
   • Retrieve cluster statistics using the _cluster/stats endpoint.
2. Index Manipulation:
   • Create an index with specific settings.
   • Delete an index.
   • Open and close an index.
   • Enable read/write on an index.
   • Reindex data from one index to another.
   • Force a merge operation for better read performance.
   • Move shards within the cluster.
   • Alter the number of replicas for redundancy.
   • Disable and re-enable shard allocation.
3. Index Interrogation:
   • List aliases.
   • List indices, including their health and status.
   • List shards and their details.
   • List segments within an index.
   • Retrieve index mapping.
   • List unassigned shards.
   • Check the progress of a force merge operation.
4. Index Entry Manipulation:
   • Add an entry to an index.
5. Nodes:
   • List nodes in the cluster, including their roles and resource usage.
   • List nodes with detailed queries.
6. Search:
   • Perform a search query within an index using cURL requests.
7. Tasks:
   • List active tasks within the cluster.
   • List detailed task information.

This serves as a practical guide for managing Elasticsearch clusters and indices in the context of a Quantexa implementation, providing essential commands to effectively maintain and optimize the Elastic search environment.
