vschema

Plan and sequence Vitess resharding offline. Key-range algebra, minimal Reshard workflow computation from source/target layouts, VSchema and topology preflight, VReplication duration estimates, and a step-by-step operator runbook with verification and rollback for every step. Dry-runs plans in CI.

A production field guide for running Vitess on sharded MySQL: topology design, VSchema & routing, online DDL coordination, and observability.

A linter for Vitess VSchema JSON. Runs 30 rules over your keyspaces, vindexes, sequences and routing rules — optionally cross-checked against your CREATE TABLE DDL — and reports each problem with a stable rule ID, exact line number and fix hint. Pretty, JSON, GitHub-annotation and SARIF output. Ships as a composite GitHub Action.
