> The current windowing, batching options are rather strict: the stream is split into smaller units based on either count or time. This model is not flexible enough to e.g. describe the following semantics: provide the data from the last one second, but provide at most 1000 records.
> The concept is based on IBM InfoSphere Stream's eviction and triggering policies, while giving the user the opportunity to define policies.
