Build a replay policy from a CSV file using pandas.

Parameters:

  • path (str | Path) – CSV file path.

  • target (ReplayTarget) – Replay target, either "nodes" or "edges".

  • node_id_column (str) – Column containing node identifiers.

  • source_column (str) – Column containing edge source identifiers.

  • target_column (str) – Column containing edge target identifiers.

  • time_column (str) – Column containing replay steps.

  • value_columns (list[str] | tuple[str, ...] | None) – Optional explicit columns to copy from records.

  • node_ids (list[str] | None) – Optional explicit node identifiers to mutate.

  • node_filter (NodeFilter | None) – Optional predicate receiving (node_id, data).

  • edge_ids (list[tuple[str, str]] | None) – Optional explicit edge identifiers to mutate.

  • edge_filter (EdgeFilter | None) – Optional predicate receiving (source, target, data).

  • missing (MissingPolicyBehaviour) – Behaviour when a replay record targets a missing item.

  • start_step (int | None) – Optional starting replay step.

  • cyclic (bool) – Whether to wrap past the final available replay step.

Returns:

Stateful replay policy.

Return type:

UpdatePolicy
