🔄 Automate EXPLAIN ANALYZE for Query Diagnostics​

Integrate EXPLAIN ANALYZE into your test suite or logs to detect regressions in query performance. Wrap your ActiveRecord relation with a custom method that logs the execution plan, helping maintainers or CI catch unexpected slowdowns.

def explain_analyze(relation)
  sql = "EXPLAIN ANALYZE #{relation.to_sql}"
  puts ActiveRecord::Base.connection.execute(sql).values.join("\n")
end

explain_analyze(User.where(active: true))

Proactively monitoring plans ensures performance budgets are respected as the schema or data volumes evolve.
