Breakpoint for an SSIS package

During execution, the package will be suspended based on the break condition. This will help us to investigate the issue at that point in time. SSIS provides ten break conditions that we can enable on tasks and containers. The breakpoints dialog box will help us set this up.

Why checkpoints are used in SSIS?

Overview of CHECKPOINT in SSIS package. We can configure a CHECKPOINT file in the SSIS package to log package execution information in it. If the package execution fails, SSIS uses the information in the checkpoint file to restart it from the point of failure.

What is the purpose of package checkpoint?
