> Problem:
> Currently the Schema Registry client does not have a proper caching mechanism for Schema
IDs.  This regularly leads to users writing producers which do not reuses schema ID's and
which then crash with the following:
> Caused by: java.lang.IllegalStateException: Too many schema objects created 
> Suggested solution:  It would better if we had a proper caching mechanism in place to
prevent hard crashes.  This often leads to data loss, and the concept of reusing schema ID's
is not always intuitive to users.
