Julian Hyde commented on CALCITE-2033:
--------------------------------------
[~ransom], That's excellent news. I'm looking forward to it.
You should consider covering more features in your tests than in your reference
implementation. If so, your initial commit could have many tests disabled
(quidem supports {{!if (false) {...}}). People can then help with the reference
implementation, and can enable tests as they get the feature working.
> Support followed by in pattern definition for MATCH_RECOGNIZE

> The [doc|https://docs.oracle.com/database/121/DWHSG/pattern.htm#DWHSG8986]
> has already defined pattern operator {{Concatenation}}. For example, pattern
> {{A B}} means that events matching pattern {{A}} and {{B}} should occur
> successively. There are also many use cases which require patterns to match
> events which not occur successively.
