Felix GV commented on KAFKA-1694:
---------------------------------
[~ijuma],
Because delete topic is asynchronous, it is useful to have a way of knowing
when the deletion process is completed properly. Currently, we do an extensive
series of checks to verify this, but a lightweight approach would be
preferable. Obviously, calling createTopics is not an appropriate way of
checking if delete topic finished. This particular issue could be side-stepped
by providing a first-class synchronous topic deletion API, but at the end of
the day, it's probably useful to have a proper topic existence API regardless.
The challenge, I suppose, is that this is not a binary state, but rather a
gradient. The valid responses might be something along the lines of:
# EXISTS
# DOES_NOT_EXIST
# CREATION_IN_PROGRESS
# DELETION_IN_PROGRESS.
