Batch Processing

Process records in bounded pages with observable results

Use the framework streaming ETL process patterns for large record sets. Choose a page size that bounds memory while avoiding excessive backend round trips. Define transaction boundaries, transformation errors, and output summaries.

Test empty and multi-page inputs, mid-page failure, interruption, and retry. Record progress in durable state when restartability is required. A frontend progress display does not prove safe recovery. See the source reference for process backend steps.
