Defined in:

Overview

Swallows component failures, returning empty success instead. Useful for non-critical operations that shouldn’t block the pipeline.

On success: returns component result unchanged. On failure: returns Success({}) with empty context, discarding errors.

Examples:

Optional profile enrichment

sequence(
  create_user,
  optional(fetch_avatar_from_gravatar),  # Failure won't stop pipeline
  send_welcome_email
)

Optional cache warming

sequence(
  update_post,
  optional(warm_cache)  # Cache failure is acceptable
)
