# Bulk Data Import

Bulk data import loads large amounts of data into a database in a relatively short period of time. When you need to load a lot of data all at once, inserting one row at a time is inefficient; bulk import operations use more efficient methods.

Bulk operations might bypass triggers and integrity checks (such as constraints). Bypassing these can significantly improve data loading performance.
