> While adding metrics to Elasticsearch connector, we noticed that the
> SimpleCounter which seems like the main implementation of Counter interface
> is not thread-safe. It makes it tricky/expensive to use it in a
> multi-threaded context.
> [~SleePy] mentioned that SimpleCounter is being used in many
> performance-sensitive code paths, so instead of changing it directly, we can
> provide a new thread-safe implementation of Counter.
