Complete the code to specify the message ordering type that ensures messages are received in the exact order they were sent.
message_ordering = "[1]"
FIFO (First In First Out) ordering guarantees that messages are received in the order they were sent.
Complete the code to select the message ordering guarantee that allows messages to be delivered more than once but preserves order.
message_guarantee = "[1]"
At-least-once delivery may deliver duplicates but can preserve message order if combined with FIFO.
Fix the error in the code to correctly represent a system that guarantees no message reordering.
if system_guarantee == "[1]": process_messages_in_order()
FIFO guarantees no message reordering, so the system should check for FIFO to process messages in order.
Fill both blanks to complete the code that filters messages to ensure only those with correct ordering and delivery guarantees are processed.
if message.ordering == "[1]" and message.delivery == "[2]": process(message)
Processing messages with FIFO ordering and at-least-once delivery ensures order is preserved and messages are delivered at least once.
Fill all three blanks to complete the code that creates a message processing pipeline with ordering, delivery, and deduplication steps.
pipeline = ["[1]", "[2]", "[3]"]
The pipeline first ensures ordering, then delivery guarantees, and finally deduplication to handle duplicates.
