## Build guidelines

This is an intentionally small set of guidelines to build users and authors
to ensure we keep the build consistent. We also publish elasticsearch build logic
as `build-tools` to be usuable by thirdparty elasticsearch plugin authors. This is
also used by other elastic teams like `elasticsearch-hadoop`.

  /**
   * Returns a view of the entries stored in this cache as a thread-safe map. Modifications made to
   * the map directly affect the cache.
   *
   * <p>Iterators from the returned map are at least <i>weakly consistent</i>: they are safe for
   * concurrent use, but if the cache is modified (including by eviction) after the iterator is
   * created, it is undefined which of the changes (if any) will be reflected in that iterator.
