Couchbase Capella - Database-as-a-Service

My main use case for Couchbase Capella involves handling data, data analytics, and performing operations with flexible JSON data where low latency is required in real-time applications such as customer profiles, shopping carts, and gaming data. I completed one project in which I analyzed e-commerce data using Couchbase Capella.

In that e-commerce project with Couchbase Capella, we worked with customer data, including customer logs such as customer profiles, their orders, wish lists, and recommendations. This data is structured in JSON format with multiple categories, loyalty points, and product catalog data that includes product ID, name, brand, stock quantities, and prices. We also analyzed customer searches for products, all using Couchbase Capella, which triggered orders, updated inventory, and notified customers.

Regarding the best features Couchbase Capella offers in my experience, I can say that it includes a JSON document database, support for SQL++, high-performance auto-scaling, and vector search, as well as governance features such as security and role-based access control, which I consider to be the best features.

Couchbase Capella has positively impacted my organization by boosting time efficiency and providing fast application response due to its low-latency key-value access, which makes customer order lookups faster and is useful for high-volume transaction applications. It also allows for flexible data models and reduces application complexity, resulting in better stability.

For specifics, I can say that performance is 80% faster, with a four-fold increase in throughput requests and application availability uptime rising from 99.9% to 99.9999%. The application can now handle three times more traffic.

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.

I have been using Couchbase Capella in my organization for more than one year.

Couchbase Capella is stable in my experience, and we have not faced any issues or downtime.

We have not faced any scalability issues, as Couchbase Capella offers strong horizontal scalability, allowing us to scale the cluster by adding nodes and increasing resources as application traffic and data volume rise.

In terms of customer support, I can say that it is excellent, and we have not faced any issues.

Previously, we did not use any different solutions. We identified the use case and, having completed my certification in Couchbase, knew this was the precise solution rather than using traditional databases.

Our experience with pricing, setup cost, and licensing for Couchbase Capella was relatively straightforward because it is a managed cloud service. The initial setup primarily related to selecting cloud infrastructure, storage, workload requirements, and cluster size, similar to purchasing a traditional database license, with no licensing issues encountered.

I have seen a return on investment. The ROI can be defined in time-saving operations and improved operational efficiency. Before, the database administrator spent twenty hours per week, and now approximately fifty percent of that time has been saved, reducing it to ten to twelve hours per week. Application latency has decreased from five hundred milliseconds to one hundred fifty milliseconds, making it sixty to seventy percent faster.

Before choosing Couchbase Capella, we evaluated traditional SQL databases such as SQL Server but found them lacking in JSON support, flexibility, low latency, and access at scale, which Couchbase Capella provides, leading us to switch.

My advice to others considering Couchbase Capella would be that if your primary use case involves handling flexible JSON with horizontal scaling and near low-latency access, then you should consider Couchbase Capella. I also suggest running a proof of concept using realistic production data and traffic beforehand. I would rate this product an eight out of ten.
