Motivation
In #16417 a cache was added for caching offsets. The problem with this implementation is that in some cases, the
memory consumption can go very high and cause OOM.
Modifications
pulsar.jclouds.readhandleimpl.offsetsscache.max.sizeto adjust this, however there shouldn't be a need to tune it.Documentation
