Soumabrata Chakraborty commented on KAFKA-4912:
-----------------------------------------------
Hi [~mjsax] - I checked with the folks on the related JIRA [KAFKA-4893].
One of the alternatives that they did document was to reduce the max length
allowed for topic names from the existing 249 to 209 to avoid violating OS
directory name length restrictions when the directories are renamed as a step
for the async deletion process.
However, a better alternative that is being explored on that JIRA is to see if
this could be addressed by adding more layers to the log directory.
Either solution should resolve this JIRA. I will update back on this JIRA once
there are further updates on [KAFKA-4893]

> We should check topic name length (if internal topics, and maybe for source
> topics? -> in cause, {{topic.auto.create}} is enabled this might prevent
> problems), and raise an exception if they are too long. Cf. KAFKA-4893
