10.2 Flow Granularity

Although using one large Flow may result in slightly more efficient performance, it's advisable to use a more modular and flexible approach, creating medium or small Flows with well-defined responsibilities, and passing all the resulting interdependent Flows to a Cascade to sequence and execute as a single unit. Similarly, using the TextDelimited Scheme (or any custom format for long-term archival) between Flow instances allows you to hand off intermediate data to other systems for reporting or QA purposes, incurring a minimal performance penalty while remaining compatible with other tools.
