Matthias J. Sax updated KAFKA-7277:
-----------------------------------
Description:
Right now Streams API unversally represents time as ms-since-unix-epoch.
There's nothing wrong, per se, with this, but Duration is more ergonomic for an
API.
What we don't want is to present a heterogeneous API, so we need to make sure
the whole Streams API is in terms of Duration.
Implementation note: Durations potentially worsen memory pressure and gc
performance, so internally, we will still use longMs as the representation.
