--output-root¶

Why we added this flag: partition outputs and manifests belong in a predictable workspace so they can be shared with vectorize; this flag names that root directory.

What it does¶

• Specifies where idxr should create partition directories and the manifest.json.
• Required for every run; idxr creates the directory if it does not exist.
• Using the same output root across runs lets idxr append new partitions and reuse digests.

Typical usage¶

idxr prepare_datasets \
  --model "$IDXR_MODEL" \
  --config configs/hotfix.json \
  --output-root workdir/partitions

Tips¶

• Commit the manifest file to source control to capture a history of migrations.
• Keep the output root outside of your source tree if partitions are large; symlink the manifest back into Git if needed.
