A thistle-farm CSA backfill must replay Cosmos change history, while a live packer station should only see new changes from now on. What should the developer configure for each consumer?
Select an answer to reveal the explanation.
Short Explanation
Backfill wants the whole scrapbook; the packer only wants new pages. Point each consumer’s change-feed start where it belongs—beginning versus now. One size does not fit both jobs.
Full Explanation
Cosmos change feed consumers can customize their starting point, including reading from the beginning of the container’s history or from the current time for live-only processing. Consistency level and Spark analytics are not substitutes for choosing the feed start. Separate consumers should use start settings that match their purpose rather than forcing a single shared history position.
