When making JSON the default for HTTP API calls, I enforced an outer [ ] around the results to ensure it was valid JSON. This is also the case now even if producing ADM results.
This is sometimes not desirable. In particular, because our ADM (and JSON?) data loaders do not accept data in this format, AsterixDB is not easily round-trippable.
Suggestion: add an HTTP parameter to select whether the output should be wrapped. This would default to "true" for JSON but "false" for ADM.
