What do you mean by a custom window? Something like the OVER clause in SQL?

A custom time window is something like workdays (Monday to Friday), nature month (day 1 to day 28/29/30/31 due to month) etc.
And counting window is not rely on timestamp but count of messages. There are also two types of counting window, tumbling and hopping. You can refer to Apache Flink for more detail.
