Couchbase SDK error handling — UnambiguousTimeoutException vs AmbiguousTimeoutException, DocumentNotFoundException, CasMismatchException, DurabilityImpossibleException, SDK debug logging, sdk-doctor connectivity diagnostics, retryable vs non-retryable errors, circuit breaker, error best practices

Couchbase SDK patterns for Rust — CAS optimistic locking, retry on CasMismatch, tokio bulk operations with join_all/FuturesUnordered, atomic counters, sub-document (MutateInSpec/LookupInSpec), array operations, exists, replica reads, touch/getAndTouch, preserve_expiry, error handling

Configure and optimize Couchbase SDK connections in Rust — async/tokio cluster setup, singleton pattern, wait_until_ready, timeouts, KV CRUD (upsert/insert/get/replace/remove), expiry, durability, sub-document operations

SQL++ queries with the Couchbase Rust SDK — scope.query, cluster.query, positional and named parameters, scan consistency, deserializing rows into structs, DML (INSERT/UPDATE/DELETE/UPSERT), MutationState RYOW

Testing Couchbase Rust applications — unit testing with mockall, integration testing with testcontainers-rs, scope/collection isolation

Entry point for all Couchbase questions — routes to the right skill based on topic and language. Use for any question about Couchbase SDK connection, querying, search, transactions, analytics, field-level encryption, testing, mobile, caching, eventing, Kafka, XDCR, backup, security, or data modeling.

Introduction to Couchbase for new developers — mental model, core concepts (bucket/scope/collection/document), service map (KV vs SQL++ vs Search vs Analytics), choosing the right skill, and where to start
