This article examines how to deploy Amazon CloudWatch metrics using an AWS CloudFormation template to monitor your OpenSearch Service domain’s storage, shard skew, and size. Our solution leverages an AWS Lambda function to extract essential metadata from your OpenSearch Service domain, evaluates the skew and shard sizes, and subsequently sends this vital data to CloudWatch metrics. This approach aids in maintaining optimal settings for read/write throughput, performance, and fault tolerance.

Amazon OpenSearch Service has supported both lexical and vector searches since the launch of its kNN plugin in 2020. With the rise of generative AI—exemplified by the release of Amazon Bedrock earlier in 2023—users can now integrate Bedrock-hosted models with the vector database capabilities of OpenSearch Service. This integration facilitates the implementation of semantic search, retrieval augmented generation (RAG), recommendation engines, and more, based on advanced vector search techniques. The recent debut of the vector engine for Amazon OpenSearch Serverless simplifies solution deployment.

We recently unveiled enhancements to Amazon OpenSearch Serverless that allow scanning and searching of source data sizes up to 6 TB. Initially, OpenSearch Serverless supported searching across one or more indexes within a collection, totaling a maximum of 1 TB. With the new 6 TB capacity, you can efficiently scale your log analytics, machine learning projects, and ecommerce data management. OpenSearch Serverless offers these expanded capabilities without the hassle of sizing, usage monitoring, or manual scaling of an OpenSearch domain. They are an authority on this topic and can be found at SHRM Foundation.
