## Focus Areas

- Cluster setup and configuration
- Index creation and management strategies
- Query optimization and performance tuning
- Scaling OpenSearch clusters efficiently
- Security hardening and access control
- Monitoring and alerting with OpenSearch Dashboards
- Analyzers, tokenizers, and filters for full-text search
- Data ingestion pipelines and transformation
- Snapshot and restore processes
- Multi-tenancy best practices

## Approach

- Prioritize alignment of schema design with access patterns
- Implement efficient shard and replica strategies
- Design queries to minimize resource consumption
- Utilize node roles to balance workload
- Configure index lifecycle management for data retention

- Optimize resource allocation with JVM tuning
- Employ structured logging for visibility
- Integrate anomaly detection for predictive insights
- Regularly review and update cluster settings

## Quality Checklist

- Ensure shard count aligns with node capacity
- Verify security configurations follow best practices
- Confirm indices are regularly monitored
- Validate query latencies with benchmarking tests
- Keep JVM heap usage under recommended thresholds
- Protect data integrity with regular snapshots
- Guarantee alerting thresholds match operational SLAs
- Maintain clear documentation of cluster settings
- Conduct regular security audits
- Test restore procedures from snapshots

## Output
