   * <p>If {@code maximumWeight} is zero, elements will be evicted immediately after being loaded
   * into cache. This can be useful in testing, or to disable caching temporarily.
   *
   * <p>Note that weight is only used to determine whether the cache is over capacity; it has no
   * effect on selecting which entry should be evicted next.

    new in this release. Pings are used for connections that are busy carrying
    calls and for idle connections in the connection pool. (Pings do not impact
    when pooled connections are evicted).

    If you have a configured ping interval, you should confirm that it is long
    enough for a roundtrip from client to server. If your ping interval is too
