Featured Reviews

Antonio Tringali - PeerSpot reviewer
Open source with extensive documentation and a University for training
I am a freelancer. A client of mine wanted a solution that would allow them to scale yet not abandon the familiar PostgreSQL front-end (and rewrite a part of their source code). Scalability aside, CockroachDB is a fine way forward from PostgreSQL and is not changing the client source code part of the system. If you are lucky and you do not use newer features from recent versions of PostgreSQL or PostgreSQL extensions, it's fine. There are nice-to-have features for big organizations like regional tables. At the moment, my client simply does not use these. However, the serverless offer from CockroachDB is reacting well as data grows.

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 most valuable feature is that CockroachDB is a distributed database, which can deploy nodes running in different regions."
"The tool's most valuable feature is node syncing, which takes only 0.54 milliseconds."
"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."
"The availability and the easy to use feature is the most valuable. The documentation is also good."
"The product has valuable security features."
"The subset of SQL that my client is using is completely supported."
"The best feature of CockroachDB is the ability to keep the nodes in different locations."
"The most valuable features of the solution are its resiliency features and the geo-partitioning capabilities."
"The best feature of Milvus was finding the closest chunk from a huge amount of data."
"Milvus has good accuracy and performance."
"I like the accuracy and usability."
"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."
 

Cons

"The platform could be more extensible."
"CockroachDB needs to improve store processes."
"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."
"Cockroach does not support all types of protocols. I need to improve it myself to support a CouchDB on my network."
"I find the serverless offer a bit confusing."
"The initial setup and pricing could be improved."
"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."
"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."
"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 has higher resource consumption, which introduces complexity in implementation."
"Milvus' documentation is not very user-friendly and doesn't help me get started quickly."
 

Pricing and Cost Advice

"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."
"I've used CockroachDB at a small scale on the free accounts because we are only testing."
"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 solution's pricing is not cheap. However, the good thing is that customers are willing to pay for it if they want it."
"Milvus is an open-source solution."
"Milvus is an open-source solution."
