After a restart, a city’s smart-meter consumer must resume reading an OCI Streaming partition without replaying the entire retention window. Which concept marks the consumer’s place in that partition?
Select an answer to reveal the explanation.
Short Explanation
An offset is a bookmark in the chapter you were reading—close the book, reopen it, and continue from that page. Every message in a Streaming partition has an offset; consumers resume from it after a restart, enabling replay and pick-up-where-you-left-off behavior. Offsets are not Queue receipts and not Events rule IDs.
Full Explanation
In OCI Streaming, each message in a partition has an offset. A consumer or consumer group resumes from an offset after a restart. Offsets provide replay and continued consumption from a known position in the partition. They are distinct from OCI Queue receipt/visibility semantics and from OCI Events rule identifiers. Design around offsets when you need durable progress tracking in a stream.
