Alberto Marchetti, a full-stack developer, outlines a method for creating a distributed timed-tasks system using Couchbase and Go, leveraging Couchbase's indexing and locking features to manage task execution in a multi-node environment. The system allows tasks to be scheduled with an execution time specified in milliseconds, using a distributed architecture to prevent multiple workers from processing the same task by employing pessimistic locking. The proposed solution involves querying the database for tasks ready to be executed, locking them for processing, and then deleting them upon completion. Marchetti discusses the use of Couchbase's CAS (Check and Set) feature to ensure document version integrity and optimize task processing with query-specific indexes. He also addresses the potential for further enhancements, such as error handling and retry mechanisms, to improve system reliability. This approach demonstrates a scalable way to manage timed tasks across distributed systems, with practical code examples and considerations for multi-node setups.
