TASK_CHUNKING

• Origin: official
• Status: supported
• Summary: Chunked integer task parameters (CHUNK[INT]).

Motivation

Lets a step expand an integer range into chunks rather than one task per value, so large frame ranges become a manageable number of tasks.

Schema

A task parameter may use the CHUNK[INT] type. The template must declare TASK_CHUNKING in its top-level extensions list.

Validation

• Declaring CHUNK[INT] without TASK_CHUNKING in extensions is rejected (/steps/{i}/parameterSpace).
• TASK_CHUNKING may be declared without using CHUNK[INT]. See internal/openjd/validate.go (validateExtensions).

Worker behavior

Chunked expansion is implemented in internal/openjd/expand.go; tasks carry the chunk's range to the worker.
