Using Autonumber in Couchbase

Ratnopam Chakrabarti, a software developer at Ericsson Inc., has been working on IoT and machine-to-machine technologies for several years. He is currently exploring ways to generate unique keys in an orderly sequential fashion using database sequences or UUIDs. In the context of Couchbase, a popular NoSQL database, Ratnopam discusses how to set up a bucket to store data with auto-generated sequence numbers, which can be used as primary keys for documents. He explains that Couchbase uses "counter" documents to handle sequence generation and demonstrates how to initialize a counter document with an initial value and use it to generate sequential IDs for inserting product data into a bucket. The code is written in Java using Spring Boot and Spring Data Couchbase dependencies, and the same concepts can be applied to other Couchbase client SDKs.
