Couchbase FTS and N1QL: A Practical Pattern for Search-First Apps
Use Couchbase Full-Text Search to shortlist document IDs by relevance, then fetch full documents with N1QL. A practical pattern for search-first applications that avoids expensive bucket scans.
Couchbase Scopes and Collections: Logical Isolation Without Bucket Sprawl
Couchbase scopes and collections offer logical isolation inside a bucket, but memory, flush, and replicas stay bucket-wide. Learn how N1QL keyspaces, per-collection indexes, and RBAC paths work, and when to choose collections over separate buckets.
Speeding Up Ad‑Hoc Queries in Couchbase with Targeted Secondary Indexes
Learn how to add a Couchbase secondary index that turns expensive full‑bucket scans into fast index‑only lookups, with a concrete example, verification steps, and trade‑offs.
Couchbase N1QL: Replacing Deep OFFSET with Cursor-Based Keyset Pagination
Deep OFFSET pages in Couchbase N1QL scan and skip rows, degrading as page depth grows. This guide shows how to build a covering composite index, encode a cursor from the last sort key and unique tiebreaker, and verify the plan with EXPLAIN.
Optimizing Couchbase Query Performance with Targeted GSI Indexing
Learn how to replace inefficient Primary Indexes in Couchbase with Global Secondary Indexes and Covering Indexes to eliminate data fetches and reduce query latency.
Couchbase N1QL Prepared Statements: What the Plan Cache Actually Buys You
Prepared statements let Couchbase N1QL reuse a query plan instead of re-parsing every request. Here is the PREPARE/EXECUTE cycle, a reproducible example, and the stale-plan trade-off.
