Go Database Refactored to Eliminate Incompatible Storage Format, Reducing Code Bloat and Maintenance Challenges

The Decision to Delete: A Necessary Evil Deleting 100k lines of production code—roughly 20% of our Go database’s codebase—wasn’t a decision made lightly. It was the culmination of a pragmatic, evidence-driven process to address a systemic issue: the burden of supporting two incompatible storage formats. This section dissects the rationale behind this drastic measure, rooted in the mechanical realities of codebase evolution, technical debt accumulation, and the long-term viability of the system. The Mechanical Strain of Dual Formats At the core of the problem was the duplication of logic required to support two storage formats. Each format demanded distinct serialization, deserialization, and querying mechanisms. This wasn’t just about writing extra code—it was about the friction introduced into the system. For example, a query operation had to branch into format-specific paths, each with its own edge cases. This branching logic acted like a thermal bottleneck in a mechanical system: it
