Protobuf metadata cache and x-site
by Galder Zamarreno
Hi,
We have an issue with protobuf metadata cache.
If you run in a multi-site scenario, protobuf metadata information does not
travel across sites by default.
Being an internal cache, is it possible to somehow override/reconfigure it
so that cross-site configuration can be added in standalone.xml?
We're currently running a periodic job that checks if the metadata is
present and if not present add it. So, we have a workaround for it, but
it'd be not very user friendly for end users.
Thoughts?
Cheers,
Galder

Public cluster discovery service
by Sebastian Laskawiec
Hey Bela,
I've just stumbled upon this:
https://coreos.com/os/docs/latest/cluster-discovery.html
The Etcd folks created a public discovery service. You need to use a token
and get a discovery string back. I believe that's super, super useful for
demos across multiple public clouds.
What do you think about that? Perhaps we could implement an ETCD_PING and
just reuse their service or write our own?
Thanks,
Seb

CLI hangs for huge cache if RocksDB is used
by Sergey Chernolyas
Hi!
I am using RocksDB Cache Storage. I faced with problem that CLI/Web hangs
long time before open information about all caches.
I uploaded to one cache 30_000_000 objects. Last versions of RocksDB has
property 'rocksdb.estimate-num-keys'. The property contains count of keys.
I supported the property in method RocksDBCacheStore.size .
But ... performance of CLI/Web changes a little.
How I can fix a problem with CLI/Web performance ?
A lot of thanks!
