January 2025 performance snapshot for 0xPolygonHermez/cdk-erigon. What was delivered: - Datastream version handling cleanup: removed the datastream version flag and related configurations, removed the DatastreamVersion constant, and hardcoded the version to 3 across the system. This standardizes protobuf-encoded datastream version usage and reduces configuration drift. - Commits supporting this work: 33e044c8fd795a5cc38ca44c2595792790a08bd4; 6bdb3fae0db7f1dbb6f6a825705f0210ee2b2216; 732c852920fa75a7a1589ce754478cdb29d6da45; d76e1903bd1d5b259805f5269d29fed6c70c372f - Documentation and developer tooling enhancements: expanded documentation for tools (Hack, Allocs, RPC Checker, Scripts) and organized zk debug tooling docs to improve developer experience and onboarding. - Commit: 3985da41b43fc373d7ae6cc7375261f1697598bd - Test suite cleanup: simplified client initialization in tests by removing an unnecessary zero-value parameter, reducing test boilerplate and improving reliability. - Commit: 9d5accf0ae29dd25eb0d204b5a0352080b6aa1ae Key outcomes and business value: - Reduced configuration surface area and risk of misconfigured datastream versions, enabling more deterministic build and runtime behavior. - Accelerated onboarding and developer productivity through clearer tooling docs and structured zk debug guidance. - Improved test reliability and CI speed by removing unnecessary test setup noise, enabling faster feedback cycles. Technologies and skills demonstrated: - Go refactoring and code cleanup, protobuf version management, and cross-cutting configuration hygiene. - Documentation tooling and developer experience improvements, with emphasis on consistency across tooling docs. - Test design simplification and maintenance-focused engineering.
