#parallel? ⇒ Boolean

Disable table-level parallelization for push operations to respect foreign key dependencies. Tables must be loaded in dependency order (as specified in table_order.txt manifest) to avoid FK violations. Intra-table parallelization is still enabled and safe.

Returns:

  • (Boolean)
