Composite indexes beat multiple single‑column indexes for multi‑column filters, but only if column order respects the leftmost prefix rule and equality columns come before the range column.
Copying RSpec tests across multiple spec files becomes a maintenance nightmare. Shared examples let you write a single test suite that can be applied to any number of classes, keeping your spec suite DRY while guaranteeing interface consistency.
