`LongAdder` performs better than `AtomicInteger` when under contention from many threads. Since it's possible that many Interactive Query threads could create a large number of `KeyValueIterator`s, we don't want contention on a metric to be a performance bottleneck. The trade-off is memory, as `LongAdder` uses more memory to space out independent counters across different cache lines. In practice, I don't expect this to cause too many problems, as we're only constructing 1 per-store. -- This is an automated message from the Apache Git Service.
