"Why is our service slow?" "I don't know, the heap is only 200MB". "But we're allocating... wait, how much?" "12 terabytes". "...in how long?" "30 seconds profile". That's when we realized: we weren't running a service. We were running a garbage factory that occasionally served API requests. The Go garbage collector was heroically trying to clean up our mess, and we were blaming it for not cleaning fast enough. This deep dive into GC internals, profiling tools, and production war stories will teach you how to stop fighting the garbage collector and start working with it.

CouchLens is a browser-based tool for analyzing Couchbase N1QL query performance. It parses system tables, extracts execution plans, and generates insights to help database administrators find performance bottlenecks without sending data to external servers. This post explains what it does, how to use it, and what features are coming.

Working with Couchbase for the past year and a half has been more than just learning a database. It has been an exercise in system thinking: seeing how indexes, queries, consistency, and durability interact, and how small design choices ripple through performance and reliability. This essay is my personal notebook from that journey. It is technically dense because Couchbase demands precision, but it is also reflective because the lessons extend beyond one database. Understanding how array indexes multiply entries, why compound index order matters, or how query consistency flags change latency is not just about Couchbase, it is about learning to think in terms of systems, trade‑offs, and consequences.
