In this post, we outline the steps to copy data between two indexes in the same OpenSearch Serverless collection using the new OpenSearch source feature of OpenSearch Ingestion. This is particularly useful for reindexing operations where you want to change your data schema. OpenSearch Serverless and OpenSearch Ingestion are both serverless services that enable you to seamlessly handle your data workflows, providing optimal performance and scalability.

This post takes a step-by-step approach to showcase how you can use Retrieval Augmented Generation (RAG) to reference real-time tweets as a context for large language models (LLMs). RAG is the process of optimizing the output of an LLM so it references an authoritative knowledge base outside of its training data sources before generating a response. LLMs are trained on vast volumes of data and use billions of parameters to generate original output for tasks such as answering questions, translating languages, and completing sentences.
