> In SPARK-50302, we modified the indexing logic for TWS variables with TTL. As
> part of these changes, we made the `numRowsRemoved` parameter represent the
> number of logical state entries that were evicted as a result of TTL
> expiration. However, the `numRowsRemoved` parameter, by its name, should be
> about the number of underlying state store _rows_ that were removed. This is
> a physical metric, not a logical metric.
> The logical metric that represents TTL expiration is
> `numValuesRemovedDueToTTLExpiry`, and that can be used for non-physical
> metrics. This fix should be made across all state variables—value, map, and
> list.
