Provides developer-friendly environment with robust security and cost-efficiency
The platform should provide a UI feature where users have the ability to manage it. The CockroachDB platform should have a chatbot where users can inquire about pricing or seek solutions for queries, rather than relying on email support. The current UI only provides SQL playground, which is technical. There should be a UI playground where users with limited technical knowledge can run and update queries, similar to phpMyAdmin or Adminer. Latency optimization could be improved for globally distributed applications, particularly in query routing. For multi-region deployment, CockroachDB requires at least three plus replicas across data centers to achieve strong consistency across regions, which increases infrastructure costs including compute, storage, and networking. The disadvantages include cost-efficiency with multi-region deployment and schema migration speed, which should be faster compared to other drivers. The query optimizer should handle complex queries better through the UI interface.

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.

Quotes from Members

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

Pros

"The initial setup and deployment are simple."
"The most valuable feature is that CockroachDB is a distributed database, which can deploy nodes running in different regions."
"The subset of SQL that my client is using is completely supported."
"What I like best is its ability to solve data residency issues. The main advantage is auto geo partitioning, built into the product. This means we don't have to spin up separate servers in each region, which would be much more costly."
"CockroachDB is highly reliable."
"I use CockroachDB to test big data samples and to create the best structure for databases. We have four users and required 10 people for deployment and maintenance."
"The most valuable features of the solution are its resiliency features and the geo-partitioning capabilities."
"The tool's most valuable feature is node syncing, which takes only 0.54 milliseconds."
"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."
"The solution is well containerized, and since containerization is quick and easy for me, I can scale it up quickly."
"I like the accuracy and usability."
"The best feature of Milvus was finding the closest chunk from a huge amount of data."
 

Cons

"The closer they can make CockroachDB to being completely compatible with Postgres, the better. It's almost compatible, but not completely. If it was, it would be nice to just be able to use Postgres libraries without any fiddling."
"I would like CockroachDB to have more compatibility with PostgreSQL, especially with the connection string and technical integrations."
"I find the serverless offer a bit confusing."
"The platform could be more extensible."
"I think the engine itself could be improved. If you miss a partition key, it should be able to be modeled. This is where AI could be really helpful. For example, if a user is from Australia, the system should know to look for their data there first instead of searching in the US or another continent."
"For multi-region deployment, CockroachDB requires at least three plus replicas across data centers to achieve strong consistency across regions, which increases infrastructure costs including compute, storage, and networking."
"The product must improve its disaster recovery features."
"Cockroach does not support all types of protocols. I need to improve it myself to support a CouchDB on my network."
"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."
"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."
 

Pricing and Cost Advice

"I've used CockroachDB at a small scale on the free accounts because we are only testing."
"The solution's pricing is not cheap. However, the good thing is that customers are willing to pay for it if they want it."
"The product's price depends on the user's company and the contract model they enter into with CockroachDB. Depending on the contract model one enters into with CockroachDB, the product may or may not be expensive."
"The platform is affordable even for the enterprise version. It provides value for investment in terms of performance."
"The pricing is good but can be made cheaper. I would rate the pricing a five out of ten."
"Milvus is an open-source solution."
"Milvus is an open-source solution."
