FIFO Ordering

Supporting FIFO (First In, First Out) behavior for Entries is a critical requirement when building messaging systems or implementing master-worker patterns. Users should be able to get Entries in the same order in which they were written. GigaSpaces supports both non-ordered Entries and FIFO ordered Entries when performing space operations.
