---------------------------------------------------------------------
bq. for the new ClientRequestMetrics, we should track tombstone and size aborts
separately
they are tracked at the keyspace/table level differently; you are saying the
global one should as well? if so did you want a tombstone abort and read size
abort?
so
{code}
aborts = Metrics.meter(factory.createMetricName("Aborts"));
abortTombstones = Metrics.meter(factory.createMetricName("AbortTombstones"));
abortReadSizes = Metrics.meter(factory.createMetricName("AbortReadSizes"));
{code}

> We currently will abort queries if we hit too many tombstones, but its common
> that we would want to also warn clients (client warnings) about this before
> we get that point; its also common that different logic would like to be able
> to warn/abort about client options (such as reading a large partition). To
> allow this we should add a concept of low/high watermarks (warn/abort) to
> tombstones and coordinator reads.
