------------------------------------------
Summary: Implement metric for inserted/removed to cache group
bytes count
Key: IGNITE-27687
URL: https://issues.apache.org/jira/browse/IGNITE-27687
Project: Ignite
Issue Type: Improvement
Reporter: Aleksey Plekhanov
Assignee: Aleksey Plekhanov
Users often ask about a metric that would show cache size or cache group size
in bytes. Such a metric exists for persistent clusters, but calculating size in
bytes is problematic for an in-memory cluster (see IGNITE-25766).
However, it's relatively simple to implement metrics like "bytes inserted into
cache" and "bytes removed from cache" (since restart). Besides being useful by
themselves, these metrics could also be used to estimate approximate cache size
in bytes for an in-memory cluster (without additional data structures).
