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.

Offers good performance to users
The tool lacks to offer AI features. In the future, I would like the product to offer AI features to users. Nowadays, we are creating small acronyms for our SQL Server. We put some templates. If I just put your name and stop it, the entire cloud can be explored, but such features are not there in Google Cloud Spanner. As a layman rather than a developer, if I create a tool or a procedure. If I write a procedure and then when you describe a procedure, a dummy procedure will be written for you, and it will be available for you as a template in SQL Server, but such kind features are not there in Google Cloud Spanner.

Quotes from Members

Pros

"The initial setup was straightforward."

"It is a very scalable solution."
"The solution is stable and reliable."
"Google Cloud Spanner is stable."
"The application deployment in the cloud is the best feature of the infrastructure."
