wtf is haystack-core-integrations?

This repository is a collection of extra building blocks for Haystack, a framework for building search and question-answering systems. Think of it as an expansion pack that adds new tools and connections so Haystack can work with more data sources, file types, and services. Haystack itself is designed to help you create systems that can search through large amounts of text, answer questions based on your documents, or build chat experiences that understand your specific data. The core software provides the basic pipeline, but real-world projects often need to connect to specific databases, read specific file formats, or use specific cloud services. That is where these additional packages come in. Each one acts as a plug-in that slots into the main framework, extending what it can do without you having to build those connectors from scratch. A product manager prototyping an internal knowledge tool might use these packages to connect Haystack to a particular database the company already uses. A founder building a customer support bot could use one of the integrations to let the system read documents stored in a specific cloud storage service. In both cases, the benefit is skipping the custom engineering work and getting a working pipeline faster. The README doesn't go into detail on which specific integrations are included or how to use them. Based on the repository description, the packages cover things like document stores (where your searchable text lives) and components (modular pieces that do specific jobs in a search or answering pipeline). If you are already using Haystack and find that it doesn't support a particular service or format out of the box, this collection is where you would look for a ready-made connector.
