Sybase CEP uniquely distinguishes every row, even where multiple rows have the same row timestamp value.
Every row arriving in the Sybase CEP Engine is processed as if it arrived at a unique moment in time, even if its row timestamp appears to indicate that it arrived at the same time as other rows. The sequence in which the rows are processed is determined by the order in which the rows actually arrive in the Sybase CEP Engine. This applies to rows that arrive in the same data stream, as well as rows that arrive in different data streams of the same application.
