N1QL is a powerful query language developed by Couchbase for use with Couchbase Server, providing a common query language and JSON-based data model for distributed document-oriented databases. It allows developers to interact with JSON in Go when the schema/structure of the document is known in advance, but struggles with dynamic queries built at runtime or unknown JSON structures. The Go SDK provides tools to handle these scenarios, enabling developers to issue N1QL queries with Couchbase and retrieve results in a flexible and efficient manner. By using N1QL with Couchbase and Go, developers can build scalable and high-performance applications that take advantage of the power of distributed document-oriented databases.
