Provides quick and easy containerization, but documentation is not very user-friendly
Milvus' documentation is not very user-friendly and doesn't help me get started quickly. Chroma DB provides super user-friendly documentation, enabling new users to get started quickly. Chroma DB's setup doesn't have many dependencies, whereas Milvus usually comes with some dependencies because of the way it needs to be deployed. Unlike Milvus, it's very easy to do POCs with Chroma DB.

Semantic search has transformed client sites and drives faster projects with higher conversions
Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start. The SQL foundation, REST API, documentation, and integration with all the AI tools made it easier. However, understanding embeddings, index types, similarity metrics, and how SQL and vector hybrid queries work, as well as the RLS policies for vectors, required some time to learn. I do not have many things to point out, but a couple of areas for improvement come to mind. For index optimization guidance, clearer instructions on when to use IVFFlat versus HNSW indexes would be helpful. Additionally, having a built-in embedding generation capability would simplify the workflow, as currently, I use external services such as OpenAI or Hugging Face for that purpose.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The best feature of Milvus was finding the closest chunk from a huge amount of data."
"The solution is well containerized, and since containerization is quick and easy for me, I can scale it up quickly."
"Milvus has good accuracy and performance."
"Milvus offers multiple methods for calculating similarities or distances between vectors, such as L2 norm and cosine similarity. These methods help in comparing different vectors based on specific use cases. For instance, in our use case, we find that the L2 distance works best, but you can experiment with different methods to find the most suitable one for your needs."
"I like the accuracy and usability."
"Using Supabase Vector, I was able to set it up in a couple of days, got it validated, and started working on building up the algorithm on top of that."
"Supabase enables us to lower the skill floor while keeping the ceiling high."
"Previously, 50% of searches returned no results or irrelevant products, but we changed that to 90% of searches returning relevant results, which led to a 30% increase in search-to-purchase conversions for the e-commerce client and was a big win for us."
"When I got to know about Supabase Vector, I fell in love with it since it worked for what I was using it for, and I just stuck to it."
"Supabase Vector rapidly increases the speed and efficiency with which I search through a database, helping with my data analysis tasks."
"We completed what we initially estimated as a fifteen-day job in just three days, thanks to the Supabase dashboards and triggers."
"I feel Supabase Vector is doing a very great job in reaching out to companies and helping them, and I believe every new entrepreneur who wants to build their own software product should be using Supabase Vector because I think it's the best vector database out there."
"Supabase Vector positively impacts my organization by reducing the cost of the LLMs."
 

Cons

"Milvus could make it simpler. Simplifying the requirements and making it more accessible. It could be more user-friendly."
"Milvus has higher resource consumption, which introduces complexity in implementation."
"Milvus' documentation is not very user-friendly and doesn't help me get started quickly."
"I've heard that when we store too much data in Milvus, it becomes slow and does not work properly."
"I think the support system can be better because after Supabase Vector stopped working in India, there is no support."
"It would be nice if all of this could be integrated all in one place with Supabase."
"My experience with Supabase Vector's performance at scale indicates that it operates excellently at small scales, but as we move toward larger scales, such as multi-million vectors, it requires careful engineering to maintain predictable performance, with challenges such as query plan complexity and latency variance."
"For advanced production use with millions of embeddings, it's necessary to be thoughtful about indexing such as HNSW or IVFFlat and hardware sizing to keep query times fast."
"One area for the solution improvement is the inclusion of more sample code in various programming languages, particularly PHP."
"One improvement I feel Supabase Vector could benefit from is that Supabase SDK stands out when comparing with a conventional Postgres SDK, and it would be even nicer if we could have a more direct way for access."
"Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start."
"When setting up a database, a PostgreSQL instance, which is the most popular use of Supabase, instead of having to go and write and run an SQL line to create a pgvector on Supabase, it would be nice if the person creating the database for the project could just be asked with maybe a checkbox whether they want a vector database or not."
