The columns method now batches table reads instead of hammering the database one table at a time, slashing statements by 50 percent on schema dumps.

Rails merged a critical optimization [1] that rewrites how the schema introspection layer reads column metadata. The columns method now accepts a list of tables, collapsing what was 250 separate database statements into a fraction of that load on large databases. This is a follow-up to earlier schema reader work [1] that systematically eliminated the per-table tax. The merge also includes fixes for initializable collection delegation [2], file field tag accept arrays [3], and documentation cleanup [4]. Across the ecosystem, routine dependency bumps landed in tailwindcss-rails [5] and rails-html-sanitizer [6] as zizmor-action updated to bundle zizmor 1.29.0. The Rails website removed its suggestion form [7] due to bot abuse.

Action items

→ Pull latest rails to capture the schema cache optimization on your next deploy rails/rails [plan]
