Hi

I have a question I'd like to discuss, if you guys aren't to busy prepping
for Ubucon.. :)

I've found a number of Java projects where, in order to communicate for
example with Kafka, they require the Kafka Java libraries for that specific
version. For the moment, I solve this by downloading the libraries from a
deployed Kafka installation and include them in the Charm. However, this
has the disadvantage that everytime the Kafka charm version changes, I have
to update the libraries in all the charms that connect to Kafka. It would
be better if there was a way to send these libraries over the connection.
This way, a Charm that can connect to one version of Kafka has a very high
chance of being able to connect to the next version.

So my question is: Is there a way to send large binary files between
Charms? Or is this problem better solved by using a subordinate
kafka-plugin Charm like the Hadoop Charms do?



Kind regards
