Provides quick and easy containerization, but documentation is not very user-friendly
We use Milvus mostly for RAG (Retrieval-augmented generation) Since Milvus is an open-source solution, I can use it without worrying about licenses or costs. The solution is well containerized, and since containerization is quick and easy for me, I can scale it up quickly. Milvus' documentation…

Transaction processes are fast and good replication capability
Use cases include querying data warehouses and databases to fetch data for clients already working on PostgreSQL.  We also use Postgres for building reports It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping. The query speed is fast, and the…

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."
"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 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 performance is good."
"The solution is scalable, it is very good."
"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."
"The most valuable feature is the performance."
"We managed to reduce the storage space needed to 10% of the original size, without affecting data integrity, and we significantly improved the performance."
"It's quite scalable."
"It's a useful solution, that can be widely used."
"PostgreSQL is very easy to use. I have experience in Oracle SQL and PostgreSQL uses the same syntax which makes it is easy for me to develop."
 

Cons

"Milvus could make it simpler. Simplifying the requirements and making it more accessible. It could be more user-friendly."
"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."
"Milvus has higher resource consumption, which introduces complexity in implementation."
"PostgreSQL’s performance could be improved."
"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 find it difficult to get connectors on the tool. For example, .NET has only one free provider in PostgreSQL. I need to pay the provider if I need something more sophisticated features. Other languages like PHP and Java have good community support. We need community support for .NET."
"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."
"PostgreSQL doesn't have a feature for temporal SQL, which is useful for gathering versions of data. This feature should be included in PostgreSQL. This feature is available in MariaDB, SQL Server, Oracle Database, and DB2."
"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."
"Integration with other platforms could be improved."
"Postgres should focus on building a stronger knowledge base. They also need to expand their integration capabilities, so more tools and resources are available to manage it."
 

Pricing and Cost Advice

"Milvus is an open-source solution."
"Milvus is an open-source solution."
"It is free, but if you need support, you can go for the commercial version called EnterpriseDB. They provide paid support, and they can even do hosting for you if you want standby and support."
"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."
"It is free. There is no license on it."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"We are using the free version of PostgreSQL."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"The licensing model is good."
"The solution requires a license."
