March 2026 performance snapshot for oxidecomputer/omicron. The month centered on delivering core database schema integrity and consistency improvements, plus substantial enhancements to the test framework to increase reliability and reduce flaky behavior. Key features delivered: - Database schema integrity and consistency improvements: enforce NOT NULL on critical columns (e.g., user_provision_type) and align time_created/time_modified semantics across the model and DB layers. - Schema parity and column-order standardization: aligned column order across major tables (including bgp_config, bgp_peer_view, vpc, instance, sled_underlay_subnet_allocation, vmm, sled_instance, etc.) to resolve differences between Diesel models and CRDB. - Data model updates: incorporated new fields (time_created/time_modified) and aligned related schemas, including BGP TTL min_ttl alignment with the CRDB schema. Major bugs fixed / reliability improvements: - Unbroken database tests and improved test error messages to reduce RTTs in CI; fortified Diesel vs CockroachDB schema alignment tests; introduced expectorate-based auto-generated SQL tests to prevent drift. - Hardened data migration and test scaffolding to reduce flake and race-condition susceptibility (per-migration test organization, stabilized tear-downs, and deterministic test data). - Additional fixes to ensure test writeback behavior on failure and to prevent false negatives in flaky environments. Overall impact and accomplishments: - Significantly reduced schema drift between Rust Diesel models and the underlying CRDB, enabling safer and faster feature deployments. - Strengthened test suite reliability, leading to earlier detection of regressions and lower CI churn. - Clearer data governance around migrations and data migrations ergonomics, accelerating future schema changes. Technologies and skills demonstrated: - Rust with Diesel ORM; CockroachDB (CRDB); advanced schema migrations; Nexus-based test harness and expectorate-generated SQL; per-migration tests; data migration ergonomics. Business value: - Higher confidence in deployments due to validated schema alignment and stable tests, reducing risk for customer-facing changes and enabling faster iteration on features. - Improved data integrity across critical provisioning and network tables, enabling more reliable reporting and operational tooling.
