> In
> {{org.apache.cassandra.cql3.QueryOptions.DefaultQueryOptions#readThresholds}}
> we always create an instance of {{DefaultReadThresholds}} when read
> thresholds are enabled. We can avoid the initialization by instead having a
> static instance of {{DefaultReadThresholds}} and always reading the values
> from {{DatabaseDescriptor}}. The estimated savings are ~32 bytes per request.
> Every request when thresholds are enabled. The proposed solution is mirroring
> the existing behavior when read thresholds are disabled.
