Selection criteria
What to compare
01Chain and contract coverage
Confirm the requirement against current docs, pricing, or support terms before it enters the shortlist. Use it as a data indexers vendor review checkpoint.
02Query and API model
Compare the same field across every product so the review does not drift into vendor-specific language. Use it as a data indexers vendor review checkpoint.
03Freshness and replay behavior
Name the team owner who will keep this check current after launch or renewal. Use it as a data indexers vendor review checkpoint.
04Export or sink support
Confirm the requirement against current docs, pricing, or support terms before it enters the shortlist. Use it as a data indexers vendor review checkpoint.
05Fallback plan
Compare the same field across every product so the review does not drift into vendor-specific language. Use it as a data indexers vendor review checkpoint.
