This instrumentation enables database client spans and database client metrics for Couchbase 2.0 operations. It automatically traces key-value operations (get, upsert, replace, remove), view queries, N1QL queries, and cluster management operations.

- **Name**: `couchbase-2.0`
- **Scope**: `io.opentelemetry.couchbase-2.0`
- **Target versions**: `com.couchbase.client:java-client:[2,3)`
- **Library**: https://github.com/couchbase/couchbase-java-client

## Telemetry

- **Metrics**: `db.client.operation.duration`
- **Span attributes**: `db.name`, `db.operation`, `db.statement`, `db.system`, `db.namespace`, `db.operation.name`, `db.query.summary`, `db.query.text`, `db.system.name`

## Configuration
