Description

Pattern without greedy: begin("A" , SKIP_PAST_LAST).oneOrMore().consecutive().notFollowedBy("B").within(Time.milliseconds(10))

Pattern with greedy: begin("A", SKIP_PAST_LAST).oneOrMore().consecutive().greedy().notFollowedBy("B").within(Time.milliseconds(10))

For sequence: <a1, 1L> <a2, 2L> <a3, 3L>, after FLINK-31040 and FLINK-31042 fixed, both of the patterns should produce [a1, a2, a3] , when currently the pattern with greedy option makes no output.
