====== Batch Processing Overview ======

Batch processing enables rapid processing of large datasets and ensures consistent results across projects, labs, and time.

Sift provides two methods of batch processing:
  - the GUI, and manually adding the library and pipelines
  - the command line
      * As a one off
      * Time-based automation
      * Directory scanning for new data automation

===== V3D Engine =====

Sift runs on Visual3D's engine, and can batch run V3D pipelines across multiple CMZs concurrently. 

**When to use**: Use the V3D Engine for processing smaller datasets, single-instance runs, or when first getting started with Sift.

===== Sift Command Line =====

The Sift command line enables large scale batch processing right from the command line.

**When to use**: Use the Sift Command Line to process large quantities of data, to run continuous automated updates over time, or, for those with experience in development.

==== Time-Based Triggers ====

Set up automatic processes to run at specific times.

**When to use**: Use this method for continuous processing on a daily, weekly, or monthly basis.
