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.
Prabir Kumar Kundu - PeerSpot reviewer

Offers robust security and availability with impressive replication capabilities
Regarding their documentation and interface, there is room for improvement. Documentation is definitely required when running multiple databases on a cluster system. The load balancer, MySQL LB, which is used to connect to the application, lacks clear documentation. When there are multiple application servers connecting to the MySQL cluster and going through the MySQL load balancer, the documentation is not user-friendly. It's there, but only technical persons with deep knowledge of the MySQL database can implement it. Most of the community users or ISVs who use MySQL don't have many technical persons or DBA experts, so they face some challenges for the high availability of connecting high available databases from high available applications. That documentation should be simplified.

Quotes from Members

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

Pros

"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."
"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."
"MySQL is the best option for the Laravel PHP framework."
"I rate the solution's stability a ten out of ten since it has been running flawlessly."
"MySQL is a very useful database which is used by a lot of companies, so it should be really good."
"The deployment process is pretty fast."
"​We use MySQL for enterprise data storage as well as part of the back-end of websites and web applications.​"
"The solution is easy to use."
"I like the JSON stuff."
"When comparing MySQL to other solutions it is easier to use and boots up faster. Additionally, when you want to query a lot of data, MySQL is better in performance."
 

Cons

"I've heard that when we store too much data in Milvus, it becomes slow and does not work properly."
"Milvus' documentation is not very user-friendly and doesn't help me get started quickly."
"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."
"As an open-source product, there isn't really any technical support available if you get into trouble or have issues."
"In terms of what I'd like to see in the next release, one thing that's always missing is dash boarding. There's no real BI tool for MySQL, like there is in Yellowfin and all the different tools that you get. They all have MySQL connectors, but there's no specific BI tool for MySQL. These open source projects have sprung up, but they're more general purpose."
"We want to continue using MySQL but it merged with Oracle and the scalage changed."
"The GUI could improve in MySQL."
"Some problems with big table operations, and a struggle to keep the servers responding in peak situations."
"Could use some additional JSON query support in the solution."
"Scalability could be improved."
"The workbench could be improved. In particular, error messages can be improved, which are horrific and completely unhelpful. I'd like to see improved parsing of errors. When you write SQL and it crashes, it usually is something completely irrelevant and not helpful. I've started to use GPT 3.5 for finding out how to do things. I got to do something a bit different, and that I found to be very useful. If there was some way to tie it into one of the new AI tools, that would probably be a good idea."
 

Pricing and Cost Advice

"Milvus is an open-source solution."
"Milvus is an open-source solution."
"The price of the solution is good because we have a good partner."
"The solution’s pricing depends on customer requirements. A license is not required for the community edition."
"Microsoft licensing for SQL Server is probably ten times more expensive. I used to work for the government, and I remember when we were looking into upgrading to the enterprise version of SQL Server 2019, the licensing was going to cost 350,000. To get the equivalent in the cloud, it was going to be about four grand to get the same processing power and everything else. With MySQL, it was going to be about 300 for the same licensing. Cost-wise, for sure, there is a huge difference. Would you prefer to pay 300 a month or 3,000 to have the same amount of data resources? You might lose a few options that you need, but it isn't worth the price difference."
"MySQL Enterprise Support is not cheap, though might still be cheaper than Oracle or SQL Server. They may not have local support depending on where you’re based, but there are many smaller agencies out there that will readily provide support. You’ll need to spend some time looking around."
"MySQL is a cheap solution."
"We are using the free version of MySQL. We prefer paying for a yearly license."
"When you know the setup will continue to grow, make sure you have the paid support."
"It is an open source platform."
