Practical overview
When it fits
Use HyDRA when developing a Python RAG prototype that needs iterative retrieval decisions, a terminal interaction loop and Milvus-backed knowledge and agent memory.
Who it is for
- Developers prototyping retrieval-augmented applications.
- Teams building question-answering or research tools over a document collection.
- Practitioners exploring multi-agent retrieval, persistent agent memory and adaptive delegation.
Documented uses
- Ingest Markdown documents into a searchable knowledge base.
- Build question-answering or research workflows that iteratively choose retrieval actions.
- Combine local knowledge-base search with live web research through specialist agents.
- Save generated reports and add saved reports back into the knowledge base.
- Use policies learned from earlier interactions to guide later agent delegation.
Requirements & limits
The repository is public and identifies an MIT license. Local setup requires Python 3.10+, a Gemini API key and Docker with Docker Compose for Milvus.
- The documented model credential is a Google Gemini API key; other model providers are not specified.
- The documented ingestion flow currently accepts Markdown files.
- Milvus is central to the stated hybrid-search and memory architecture.
- The documented user interface is an interactive terminal interface.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Set up HyDRA and prepare a Markdown knowledge base
Install the framework, configure its documented services and ingest Markdown files before using the terminal interface.
Before you start
- Python 3.10 or later
- Google Gemini API key
- Docker and Docker Compose for Milvus
- Git and pip
Steps
Start a standalone Milvus instance using the README's operating-system-specific guidance.
Clone the HyDRA repository, enter its directory and install dependencies with the command below.
pip install -r requirements.txtCopy
.env.exampleto.envand add the Gemini API key.Create the Milvus collections with the command below.
python -m src.services.milvus_setup --profile developmentPut Markdown documents in
data/and run the command below.python -m data_processing.ingest --path ./data --profile development
Expected outcome
Milvus collections are prepared and Markdown documents are ingested into the knowledge base.
Guide limitations
- The README says the ingestion process currently supports Markdown files.
- The guide documents setup and ingestion, not a successful run or deployment.
Launch the HyDRA terminal interface
Open the documented interactive interface and start a personalized conversation.
Before you start
- HyDRA repository and dependencies installed
- Milvus configured and running
- Gemini API key set in
.env
Steps
From the repository directory, launch the command below.
python main.py --profile production_balanced --user_id alexChat naturally or use
/helpto view available commands.Use
/saveto save the last generated report,/ingestto add a saved report to the knowledge base, or/newto start another conversation.
Expected outcome
The README describes an interactive terminal conversation with commands for managing sessions and reports.
Guide limitations
- The README does not specify supported models beyond the Gemini API key prerequisite.
- The command and interface steps describe documented usage, not an execution test.
Compare options for Retrieval-augmented applications
These projects document a common task and share a project role. This is a source-based comparison, not an execution benchmark or a guarantee of interchangeability.
