Featured Reviews

PranavVighe - PeerSpot reviewer
Senior Consultant Data Engineer at IRT Digital Analytics
Real-time customer analytics has boosted performance and simplified flexible JSON operations
I believe that the documentation should be increased, and features such as vector AI search and other AI capabilities need improvement for Couchbase Capella. I would say that there is a need for developer experience enhancements, including a simpler user interface, better debugging, SQL++ guidance, and more visibility into granular workload-level costs while reporting. Couchbase Capella can improve the accuracy and reliability of its AI output. Though it is not guaranteed that the large language model answer will be correct, improvements can be made by grounding the large language models and controlling parameters such as temperature to provide better results.
Ethan Lo - PeerSpot reviewer
Infrastructuer Security at Premise Data
A stable and scalable relational database that ensures a return on investment for its users
The most valuable feature of the solution is its scalability. Scalability comes with two options, among which Google Cloud Spanner can scale horizontally, compared to other relational databases that scale vertically. You can change Google Cloud Spanner's resource configuration, which is done through processing units. Suppose you set up Google Cloud Spanner initially with a hundred processing units, and then you run out of resources since your database used too much CPU. In the aforementioned scenario, you can scale up or down and face no downtime in the production phase. The solution's features are important when running a company twenty-four hours, seven days a week.
