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.

Reliable open-source database has supported our migration and improved e-commerce performance
Percona Server seems great to me overall. If I had to think of any small area for improvement for Percona Server, it would be around the proxy story. When adding a proxy to manage traffic better, we first tried SQL Proxy, but it never really worked for us, which was unfortunate because SQL Proxy offers better optimizations for read performance. We did have success with HAProxy, but it works on a network level, while SQL Proxy was designed to be SQL-aware and distribute parts of the query across the database cluster. The performance gain we were hoping for with SQL Proxy did not materialize, so we remained on the network level with HAProxy. Databases can be finicky regarding the performance they need. We had some disk I/O latency issues, which led us to use different types of nodes in our Kubernetes cluster where we provisioned Percona Server explicitly. There is a lot of IOPS happening under the hood, and while I suspect the application was not very efficient, it was also challenging to identify that we were experiencing performance issues due to disk performance. It would be helpful to clarify the metrics related to disk I/O latency so we could understand where our bottlenecks are.

Quotes from Members

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

Pros

"I like the accuracy and usability."
"Milvus has good accuracy and performance."
"The best feature of Milvus was finding the closest chunk from a huge amount of data."
"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."
"The solution is well containerized, and since containerization is quick and easy for me, I can scale it up quickly."
"In my use of Percona Server, I've found that the replication and High Availability features are the most valuable."
"Percona Server's scalability is very strong, as it features thread pooling for over 10,000 connections, scales out horizontally, and comes with XtraDB Cluster and ProxySQL, making it very effective."
"Percona Server has positively impacted my organization by allowing us to save a ton of money by not having to use RDS or Aurora in Amazon, which is the public cloud that we are in."
"Percona Server's performance when handling large data sets was significant compared to regular MySQL, and it was excellent."
"The best feature that Percona Server offers is that it was free."
"Percona Server has positively impacted my organization because it is open source, and if the official MongoDB goes in different directions or makes its product expensive, we can still use Percona Server, which serves as a sort of safety net."
"We find the product mostly stable."
"Percona Server has positively impacted my organization by reducing downtime for applications and improving backup capabilities."
 

Cons

"Milvus has higher resource consumption, which introduces complexity in implementation."
"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."
"I would like to add that the user interface is very crowded, which makes it challenging for new engineers to know where to turn, so I had to sit down and understand the documentation before I was able to manage the application myself."
"I have limited experience to provide detailed insights about needed improvements."
"Percona Server could be improved to keep pace with other flavors of MySQL, such as MariaDB, and could pivot to be Percona Server for MariaDB given Oracle's reduced investment in MySQL recently."
"I also think there should be more use cases and documentation on deploying in Kubernetes with real-life examples, as currently, the documentation is minimal, making it difficult in a production situation."
"If I had to think of any small area for improvement for Percona Server, it would be around the proxy story."
"Percona Server can be improved by addressing the lag between releasing new versions of MySQL and its Percona support, and also by enhancing the configuration of performance variables to provide more user-friendly and easier to configure options."
"It doesn't reclaim disk space when rows are deleted."
"Percona Server could be improved by adding more advanced query fields, which would be very helpful."
