Subject Re: Disadvantages of Upgrading Kafka server without upgrading client libraries?
Date Tue, 29 Nov 2016 18:06:09 GMT
The only obvious downside I'm aware of is not being able to benefit
from the bugfixes in the client. We are essentially doing the same
thing; we upgraded the broker side to 0.10.0.0 but have yet to upgrade
our clients from 0.8.1.x.
