Helps convert text and other data into a vector space but could provide detailed insights
Milvus is an open-source vector database designed for efficiently handling large-scale, high-dimensional data. It supports various types of data sources and can be deployed on your own premises, which is crucial for maintaining data security. 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. Milvus also includes its own user interface, known as the Milvus Dashboard, which allows you to visualize and manage your data, including embeddings and metadata. You can filter your data based on various criteria, including metadata and file names, which provides flexibility in data management.

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.

Pros

"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."
"Milvus has good accuracy and performance."
"I like the accuracy and usability."
"Percona Server has positively impacted my organization by reducing downtime for applications and improving backup capabilities."
"After switching to Percona Server, we were able to resolve those issues quickly."
"In my use of Percona Server, I've found that the replication and High Availability features are the most valuable."
"We find the product mostly stable."
"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 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."
 

Cons

"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."
"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."
"If I had to think of any small area for improvement for Percona Server, it would be around the proxy story."
"If Percona had flashback capabilities, it would be ideal."
"Percona Server could be improved by adding more advanced query fields, which would be very helpful."
"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."
"It doesn't reclaim disk space when rows are deleted."
"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."
