Practical overview
When it fits
Use Blaze Db when you want to operate a disk-backed vector index yourself and query it for similar items, such as products in a recommendation or semantic-search workflow.
Who it is for
- Developers building applications that need embedding-based similarity retrieval.
- Teams seeking a self-hosted vector store with server, client and CLI components.
Documented uses
- Store and index embeddings on disk.
- Retrieve similar items using cosine, Euclidean or dot-product distance.
- Create a database and query it through the CLI.
- Run batch or chunk embedding-generation processing through the CLI wrapper.
Requirements & limits
The repository is public and identifies the project as MIT-licensed. The README documents building from source with Cargo and also provides a Docker image workflow.
- The project offers cosine, Euclidean and dot-product distance metrics.
- The CLI wrapper's batch and chunk processing is specifically described for embedding generation.
- The README notes caveats in backup and restore and says lazy deletion and background reindexing need improvement.
- Published performance numbers are project-reported benchmarks and should not be treated as a guarantee for other workloads.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Create a database and query it with the CLI
Use the documented CLI commands to create a database and request the top matching results.
Before you start
- Blaze Db CLI (
blzdb) available. - A configured source named
default_srcand an embedding database.
Steps
Create the database with
blzdb create --database amazon_products_2023 --source default_src.Query it with
blzdb query --database amazon_products_2023 --source default_src --search "Wireless Bluetooth Headphones with Noise Cancellation" --top_k 10.
Expected outcome
The CLI requests up to 10 matches for the supplied text from the named database and source.
Guide limitations
- The example presumes the database and source are available; the commands alone do not prepare embeddings or configure an embedding provider.
Compare options for Vector search
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.
| Project | Documented purpose | Platform | Access and requirements |
|---|---|---|---|
| Blaze Db | Store and index embeddings on disk. | CLI, Self-hosted, Server | The repository is public and identifies the project as MIT-licensed. The README documents building from source with Cargo and also provides a Docker image workflow. |
| Llmaker | Provision a model together with vector search, embeddings, caching or observability services. | CLI, Docker, Self-hosted | The README requires Docker and lists Linux and macOS for prebuilt binaries. It also documents installation through Go or from source. The project is labeled alpha. |
| Weaviate — weaviate | Store application objects alongside vectors and retrieve similar items. | Cloud, Self-hosted, Server | The repository describes Weaviate as open source and lists Docker, Kubernetes and Weaviate Cloud deployment options. |
