Sameer Bhangale - PeerSpot reviewer
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.

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."
"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 solution is well containerized, and since containerization is quick and easy for me, I can scale it up quickly."
"The best feature of Milvus was finding the closest chunk from a huge amount of data."
"We use the solution to store tables. It is stable and performs well."
"The product's deployment is easy."
"The most valuable features are the price, stability, it is scalable and is used by our clients in small business environments, and it is a simple product to use."
"It is very scalable and comes with a bonus: no licensing issues as you scale with your databases."
"Scalable, stable, and easy to manage database system, with a straightforward installation."
"It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping."
"PostgreSQL has complete SQL dialects and is useful for writing sophisticated and complex queries. We have experience with Oracle database. My partner is experienced in DDA and he writes sophisticated SQL queries. The solution helps to get the job done in the best possible way. In today’s age, most developers do not have strong SQL knowledge or language command. They find it difficult to write even a SQL statement. These developers write cool queries which perform badly on the database end. As DBAs, we constantly urge the developers not to write bad queries, help them learn more, and write placebo commands."
"The solution has many valuable features such as it easy to use and the interface is intuitive."
 

Cons

"Milvus could make it simpler. Simplifying the requirements and making it more accessible. It could be more user-friendly."
"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 has higher resource consumption, which introduces complexity in implementation."
"The interface climate could be better."
"Instead of the installation agent downloading all the packages for the install, it should allow the user to download the packages separately on their own to do the install."
"If it was free to use, it would be the perfect solution."
"There are several features I would like to improve that aren't working as expected. It's likely that the latest version is doing something that was missed in the previous versions. For example, the output parameters — the stored procedures — is something new in PostgreSQL that Firebird has already had for a long time."
"It is possible that in the newer version this has been addressed, but I would like the deployment in microservices architecture could be improved."
"We have to set up event API, which takes a lot of events from the user."
"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."
"PostgreSQL’s performance could be improved."
