To perform a bulk load, you can use [bcp Utility](../../tools/bcp-utility.md), [Integration Services](../../integration-services/sql-server-integration-services.md), or select rows from a staging table.

As the diagram suggests, a bulk load:

- If the batch size is >= 102400, the rows are directly into the compressed rowgroups. It is recommended that you choose a batch size >=102400 for efficient bulk import because you can avoid moving data rows to a delta rowgroups before the rows are eventually moved to compressed rowgroups by a background thread, Tuple mover (TM).

If you want force a delta rowgroup closed and compressed, you can execute the following command. You may want run this command if you are done loading the rows and don't expect any new rows. By explicitly closing and compressing the delta rowgroup, you can save storage further and improve the analytics query performance. A best practice is to invoke this command if you don't expect new rows to be inserted.
