Global SyncTime

[nsulikowski]

Does Trill have one notion of time across all streams or only per stream?
If it does, is there a way to access that long property?

[James Terwilliger]

The notion of sync time is per stream, right up until any binary operator in which case they must be considered the same. That notion is entirely data-driven - there is no notion of sync time that is somehow managed by the query or the engine itself.

You can absolutely access that long property - you can lift it into your payload using an overload of Select whose lambda takes two parameters. It looks like: stream.Select((sync, payload) => ...)
