A new IRIS feature allows selective FIFO processing by assigning a calculated identifier to each message. This ensures messages with the same identifier stay in order without blocking the entire queue. The demo shows how identifiers are created via transformations or BPL, how completion hosts work, how dependencies are handled, and how safety features prevent processing issues. The feature is available in the August 2025 preview and planned for release in 2025.3.
