William Burns commented on ISPN-9033:
-------------------------------------

Although I must admit I am a bit worried about rocksDB iteration performance in general. Looking online I have found quite a few complaints about performance and even some issues where they were going to improve it but they never implemented those and let the issues close due to inactivity.

>             Project: Infinispan
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 9.2.1.Final
>            Reporter: Sergey Chernolyas
>
> 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.
