A public-works telemetry reader needs to start at a specific time in an OCI Streaming partition without deleting messages when they are read. Which construct points at that location?
Select an answer to reveal the explanation.
Short Explanation
A cursor is a finger on the map—pointing at an offset, a time, or a group’s place—without tearing the page out. Clients move cursors; Streaming does not delete a message just because someone read it. That is the opposite of Queue’s consume-then-delete model.
Full Explanation
OCI Streaming cursors are pointers to a location in the stream: a specific offset or timestamp in a partition, or a consumer group’s current position. Clients advance cursors as they read. Reading does not delete messages from the stream—retention and consumption are separate, unlike OCI Queue’s consume-and-delete pattern. Use cursors to position readers; use offsets as the underlying position numbers those cursors reference.
