Hi all,
A heads up on what is going on with https://issues.jboss.org/browse/ISPN-2281
While discussing this, Tristan and I came to the conclusion that we could avoid the need
to create some wrappers required to fulfill requirements in this JIRA, and as a side
effect, reduce the memory consumption of Infinispan servers, if we could have internal
data containers based on concurrent hash maps that took a custom function for
equals/hashCode…etc. By doing that, you could effectively have **byte[] keys and values
for maps**.
By doing that, you avoid creating wrappers (yippee!) for keys (bye bye ByteArrayKey), and
combined with a better way to pass metadata into Infinispan Caches (i.e. version) that is
stored within the internal cache entries, you avoid wrapper values too! (bye bye
CacheValue).
Pushing this even further would be to keep data and metadata separate in
the store representation too as we currently write/read marshalled
InternalCacheEntries to the stores. Probably this will have to wait for
6.0 when we overhaul the stores.
