Real-time data capture optimizes database performance but Views create problems
One of the most valuable features is real-time data capture; it optimizes database performance. I think using real-time data capture reduces job running time and the amount of data sent at once with batch loads. Replicating the same data daily isn't optimal, so real-time reception improves application performance and reduces latency.

Easy to use, and there is no need to get involved in any tedious deployment process
If you are a business building a social media app, there will be thousands of users for every such app. Each user will have a post or something. When multiple users try to hit the like button on your post or try to comment on your post, each of them would be an API request, and Supabase Vector does not charge for them like. The API requests are kind of unlimited. If you compare Supabase Vector to any of the other services like Firebase, AWS, or Azure, all the tools charge per request. From a scalability standpoint, if you are a small-scale startup and you have around 1,00,000 or 2,00,000 users, then Supabase Vector is a perfect choice for you. I have never heard about any scalability issues in the product. Scalability-wise, I rate the solution a ten of ten.

Quotes from Members

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

Pros

"The system can perform faster analysis by providing it with a lot of memory. Speed is crucial for analytics. Currently, the main reason we haven't adopted Elasticsearch is that we lack the necessary expertise to manage it."
"It has completely met our needs. It works, and it is robust. We haven't had any problems with what PostgreSQL does for us and the way it does it. That's why we've been using it for so long. We understand it, and it does the job."
"It is easy to use."
"The initial setup is quick and easy."
"It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping."
"It is very simple to manage."
"The database has excellent performance."
"Postgres is rock solid when deployed according to best practices as documented by the PostgreSQL community. When it's installed correctly, PostgreSQL is an enterprise-grade solution."
"The tool is easy to use."
"Supabase enables us to lower the skill floor while keeping the ceiling high."
"The platform's role-level security feature is quite effective for spatial data management."
"Supabase enables us to lower the skill floor while keeping the ceiling high."
 

Cons

"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."
"They need to improve the user experience of the management."
"I had some issues when I integrated with the Jupyter Notebook."
"PostgreSQL uses high memory compared to its counterparts when a highly demanding load is involved, especially one that makes many concurrent connections to the database."
"The scalability is limited."
"We have to set up event API, which takes a lot of events from the user."
"The interface climate could be better."
"It is possible that in the newer version this has been addressed, but I would like the deployment in microservices architecture could be improved."
"I think there are still many Postgres features that can be developed further by the Supabase team."
"I think there are still many Postgres features that can be developed further by the Supabase team."
"The support for React Native CLI is an area with certain shortcomings where improvements are required."
"One area for the solution improvement is the inclusion of more sample code in various programming languages, particularly PHP."
 

Pricing and Cost Advice

"The need for our customers to pay for licences is contingent on their projects and budgets."
"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."
"It is open-source. If you use it on-premise, it is free. It also has enterprise or commercial versions. If you go for the cloud version, there will be a cost, but it is lower than Oracle or Microsoft."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"Affordable solution."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"The tool is cheaply priced compared to other RDBMS providers in the market."
"We do not pay for licensing."
"As per the product's regular pricing plans, the tools are available to users for 20 to 25 USD per month."
"The solution's cost is reasonable compared to other solutions."
