While OpenSearch provides a rich set of features and capabilities out of the box, optimizing its performance, reliability, and security requires adherence to best practices.
To assist you in navigating OpenSearch we have put together an extensive guide of the best practices for OpenSearch to ensure that you get the most out of the solution. These best practices cover multiple aspects of cluster architecture, indexing, querying, monitoring, security, and more, guaranteeing that your OpenSearch deployment operates smoothly and delivers actionable insights to your organization.
What is OpenSearch?
OpenSearch is an open-source distributed search and analytics engine created for scalability, simplicity, and performance. It serves as a powerful tool for indexing, searching, and examining large volumes of data in real-time. OpenSearch is built on Apache Lucene, a commonly used full-text search library, and it offers a robust platform for a broad range of use cases such as log analytics, monitoring, search engines, and business intelligence.
Originally, OpenSearch was a community-driven fork of Elasticsearch, an open-source search and analytics engine developed by Elastic. However, it has since evolved into a separate project with its own governance and roadmap. OpenSearch intends to supply users with a fully open-source alternative to proprietary search and analytics solutions, providing transparency, flexibility, and control over their data and infrastructure.

OpenSearch Best Practices
Optimizing the utilization of OpenSearch entails adhering to a set of best practices aimed at improving performance, reliability, and security. We have listed a range of OpenSearch best practices that cover all aspects of the solution below.
Cluster Sizing and Configuration
Firstly, cluster sizing and configuration are crucial. You need to properly outline node types and hardware specifications to match your workload demands. Dedicate nodes for certain roles such as master, data, and coordinating nodes to streamline responsibilities and enhance performance. Additionally, you should determine the amount of shards and replicas for each index to stop resource overutilization and facilitate efficient cluster operation. Fine-tune network settings to ensure seamless communication between nodes to avoid latency issues and bottlenecks.
Index Management
Another vital aspect when using OpenSearch in index management. You should utilize Index Lifecycle Management (ILM) policies to automate index lifecycle operations such as rollover, retention, and deletion. Implement index shrink and split operations to manage index size and distribution effectively, to improve query performance and storage efficiency.
Data Ingestion and Pipeline
Efficient data ingestion and processing are vital for maintaining optimal cluster performance in OpenSearch. You and your team should employ bulk indexing techniques to ingest large volumes of data swiftly while minimizing overhead. Make sure to utilize ingest node pipelines to preprocess and enrich data before indexing, guaranteeing data quality and optimizing search capabilities.
Query Optimization
Query optimization is a vital practice to ensure maximum search performance. You should focus on carefully designing indices and mappings to support efficient querying. Utilize the Query DSL to construct enhanced queries, leveraging filters, aggregations, and scoring mechanisms. Regularly track query performance and use profiling tools to highlight and address performance bottlenecks.
Monitoring and Alerting
Maintaining cluster health and proactively addressing issues is made simpler by utilizing monitoring and alerting mechanisms. Track critical cluster metrics such as CPU usage, memory utilization, disk I/O, and JVM heap usage to identify anomalies and performance degradation. It’s vital to configure alerts to fire when critical events occur and thresholds are breached to notify administrators promptly to sped up time to resolution.
Security, Backup, and Disaster Recovery
Enhance the security of your OpenSearch cluster by enabling authentication and authorization mechanisms. Employ role-based access control (RBAC) to manage access to indices, documents, and cluster APIs based on user roles and permissions. Also, you should encrypt network traffic using Transport Layer Security (TLS) to protect data in transit. Ensure you enable encryption at rest to encrypt data stored on disk to prevent unauthorized access. Also, backup and disaster recovery strategies are crucial for guaranteeing data resilience and business continuity. Employ snapshot and restore functionality to create frequent backups of indices and restore them in case of data loss or corruption.
Documentation and Training
To continue the effective operation of Opensearch, comprehensive documentation and ongoing training are vital for fostering knowledge sharing and empowering administrators and users to leverage OpenSearch effectively. You should maintain detailed documentation covering cluster configuration, best practices, troubleshooting procedures, and recovery processes. As well as this, offer frequent training sessions and resources to guarantee administrators and users have the skills and knowledge to manage OpenSearch clusters effectively.
