Quotes from Members

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

Pros

"The availability and the easy to use feature is the most valuable. The documentation is also good."

"CockroachDB is highly reliable."

"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 most valuable feature is that CockroachDB is a distributed database, which can deploy nodes running in different regions."

"The most valuable features of the solution are its resiliency features and the geo-partitioning capabilities."

"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 subset of SQL that my client is using is completely supported."

"The initial setup and deployment are simple."

More CockroachDB pros

"The solution returns data quickly, and data retrieval is fast in kdb+."

Cons

"The platform could be more extensible."

"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 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."

"Cockroach does not support all types of protocols. I need to improve it myself to support a CouchDB on my network."

"CockroachDB needs to improve store processes."

"We are looking for more features to support distributed high availability and geo-partitioning."

"The product must improve its disaster recovery features."

More CockroachDB cons

"The solution should have a more user-friendly user interface."

Pricing and Cost Advice

"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."

"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 pricing is good but can be made cheaper. I would rate the pricing a five out of ten."

Overview

CockroachDB is a distributed SQL database built on a transactional and strongly-consistent key-value store. It scales horizontally; survives disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention; supports strongly-consistent ACID transactions; and provides a familiar SQL API for structuring, manipulating, and querying data.

CockroachDB is inspired by Google’s Spanner and F1 technologies, and it’s completely open source.
