Diagnosing Intermittent N1QL Latency Spikes in Couchbase with Global Secondary Indexes
Learn how to spot, diagnose, and fix periodic p99 query latency spikes in Couchbase clusters when GSI indexes are involved.
Choosing Between Deferred and Immediate Index Builds for Rollback Safety
Goal: Safe Rollback After Schema Change When applying a schema change via N1QL index updates in Couchbase, the objective is to allow a rollback to the previous index version without causing query downtime or excessive resource spikes. The two documented approaches are to create the replacement index with the WITH deferred clause and later trigger a BUILD IND
Couchbase N1QL Pagination: Consistency Issues with Concurrent Updates
Goal Retrieve a large dataset in pages while maintaining a stable order of rows. Constraints & Uncertainty LIMIT/OFFSET scans all preceding rows, leading to linear time for high offsets. Keyset pagination avoids this but its snapshot consistency during concurrent inserts, updates, or deletes is not fully documented. Without guaranteed consistency, pages
N1QL Pagination Configuration for Deep Offset Performance
Couchbase SQL++ (N1QL) employs OFFSET and LIMIT clauses to manage result set pagination. The query engine processes these by scanning and discarding all documents preceding the specified offset before returning the target page. In environments utilizing the Java SDK, this behavior can lead to linear performance degradation as the offset increases, potentiall
