Title: Message Title

Fabian Hueske commented on FLINK-5654   Re: Add processing time OVER RANGE BETWEEN x PRECEDING aggregation to SQL Ad 1) The restrictions was only meant for the supported semantics. If RANGE INTERVAL '1' HOUR PRECEDING is equivalent to RANGE BETWEEN INTERVAL '1' HOUR PRECEDING AND CURRENT ROW it will be automatically supported because we do the check on the logical operator level and not on the syntactic level, i.e., we won't notice which of both variants was used. Ad 2) I'd prefer the first option, i.e., using windowAll() this will make the behavior more transparent for the lower levels of Flink.
