Alex Baranau commented on HBASE-6411:
-------------------------------------
Some more words on incr() in registry. This may actually be OK. Or rather "not
that big a deal". I.e. to me this interface that we have:
{noformat}
public interface BaseMetricsSource {
public void setGauge(String gaugeName, long value);
public void incGauge(String gaugeName, long delta);
public void decGauge(String gaugeName, long delta);
public void removeGauge(String key);
public void incCounters(String counterName, long delta);
public void removeCounter(String key);
}
{noformat}
looks like "registry description": smth which holds metrics (allows to
add/remove them by name) and provides read/write access to them _by name_ (if
one doesn't want to deal with the specific classes/implementations of those
metrics). I.e. seems not that bad.
That is why I suggested we replace this class with the registry in the first
place. But OK to leave it.
