final class RemoteEntriesIterator extends ClusteredColumnIterator with Logging

A ClusteredColumnIterator that fetches entries from a remote bucket.

TODO: PERF: instead of fetching using getAll, this should instead open a named ColumnFormatIterator on the remote node hosting the bucket, then step through the iterator to fetch batch (or batches) at a time using Function/GfxdFunctionMessage invocations. As of now, the getAll invocation does not honour ordered disk reads, proper fault-in etc.
