Jason Brown commented on CASSANDRA-14367:
-----------------------------------------
[~dbrosius] In {{TableHistograms}} you used {{Lists.newArrayList}} instead of
{{Collections.singletonList}}. Any particular reason why?
> prefer Collections.singletonList to Arrays.asList(one_element)

> small improvement, but Arrays.asList first creates an array, then wraps it
> with a collections instance, whereas Collections.singletonList just creates
> one small (one field) bean instance.
> so a small cut down on garbage generated.
