US Patent 10572486 Data communication in a distributed data grid

A method of communicating data in a data grid. The method includes receiving, from an iterator in a data grid, a search request to search for data matching search criteria in a first memory coupled to a node. The method further includes searching, by a processor of the node, for data in the memory matching the search criteria to obtain result data. The method further includes communicating, by the processor, the result data to the iterator. The method further includes pausing communicating the result data to the iterator in view of a pause condition pertaining to the memory capacity threshold of the second memory. The method further includes, in response to a resume condition, resuming communicating the result data to the iterator.
