kazeflow partitions

Inspect partition definitions in a selected dependency closure without executing an asset body or enumerating a dynamic catalog. Entry loading is still trusted Python; see the trust boundary before loading unfamiliar source.

Synopsis

kazeflow partitions ENTRY [--target NAME ...] [--format text|json]

What it reports

For every partitioned asset in the selected closure, the command reports:

• asset name;
• definition kind;
• stable partition domain;
• accepted key format; and
• whether the definition supports an explicit bounded range.

For example, a DatePartitionDef reports its DatePartitionDef definition kind, the date domain, strict ISO YYYY-MM-DD key format, and inclusive bounded-range support. The command does not guess today, list all historical dates, or invoke asset bodies. An unpartitioned closure succeeds with an explicit empty result.

kazeflow partitions daily.py --target publish_daily
kazeflow partitions daily.py --format json

Use this command before choosing one selector for plan or run:

kazeflow plan daily.py --partition-range 2026-08-08 2026-08-10

Text and JSON outputs omit selected raw keys because this command reports definition metadata rather than work selection. JSON is a deterministic automation projection; keep diagnostics on standard error separate from successful one-document JSON output. Its typed envelope, fields, and normative schema are listed in the JSON automation contract.
