Metrics</a></h5>
- All of the following metrics have a recording level of <code>debug</code>.
- The metrics are collected every minute from the RocksDB state stores.
- If a state store consists of multiple RocksDB instances as it is the case
for aggregations over time and session windows,
- each metric reports an aggregation over the RocksDB instances of the state
store.
+ RocksDB Metrics are grouped into statistics-based metrics and
properties-based metrics.
+ The former are recorded from statistics that a RocksDB state store collects
whereas the latter are recorded from
+ properties that RocksDB exposes.
Review comment:
I elaborated on the two types of metrics. Let me know if it is better
now.
