Hi, All! I'm working on IGNITE-3443 "Implement collecting what SQL statements executed on cluster and their metrics." [1]
And I need to discuss where and how store collected metrics. I see 2 options: 1) Store metrics in a special separate replicated cache. In this case I could easily add, collect and evict metrics. But I will need somehow made this cache "system" in order to not show it for users (for example in Visor console). 2) Store metrics in system utility cache. In this case I could easily add metrics, but collecting and evicting will be not so trivial... Which way should I choose? Please, share your thoughts.
