In the article "Migrating Buckets to Collections & Scopes via Eventing: Part 1," the author explores the use of Couchbase Server 7.0's new feature, Scopes and Collections, to organize data more effectively. The piece specifically focuses on leveraging Couchbase's Eventing service to migrate documents from bucket-based storage in older Couchbase versions to the new Scopes and Collections structure, without the need for N1QL or indexes. The article includes a detailed walkthrough of setting up the necessary keyspaces and deploying an Eventing function, ConvertBucketToCollections, which processes document changes via an OnUpdate entry point. The function allows for data transformation and migration by moving documents into collections based on their type, while also offering the flexibility to enrich and modify the data during the migration process. The article also hints at a follow-up post that promises to provide a more automated approach to large-scale migrations using a Perl script.
