-----------------------------------------

Hi [~NadirX]

I understood it. But ... Can we optimize it?
For example, if cache has persistence without passivation ...  we can ask cache store about count of keys. It is fast.
I guess that we can divide the issue to several subtasks (one subtask is for each cache)

I have two caches with size more that 5 000 000 keys. All caches have cache store based on RocksDB. And ... counting take one tread and count during 10-15 minutes. I can't open Web interface for looking statistic.  I can use CLI .... but it is too long to.

> My cache configuration has RocksDB's cache. Cache has a more then 1 000 000 entries.
> And  it do usage of Web interfce and CLI impossible.
> As I have investigated, problem can be in class org.infinispan.commands.read.SizeCommand.
> {code:java}
> public Integer perform(InvocationContext ctx) throws Throwable {
>       long size = cache.keySet().stream().count();
>       if (size > Integer.MAX_VALUE) {
>          return Integer.MAX_VALUE;
>       } else {
>          return (int) size;
>       }
>    }
> {code}
> I think, the code must ask CacheStore for sizing.
