Data communication in a distributed data grid

An iterator, comprising:

• a first memory coupled to the iterator to store data, wherein the iterator is coupled to a first node in a data grid;
• a processor coupled to the first memory, the processor to:
• communicate, to a second node in the data grid, a search request to search for data in a second memory of the second node, wherein the search request comprises:
• search criteria defined by a search query from an application;
• and
• a memory capacity threshold of the first memory;
• receive, from the second node, result data of data in the second memory matching the search criteria;
• and
• pause receiving the result data from the second node in view of a pause condition pertaining to the memory capacity threshold of the first memory.

A method, comprising:

• 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, wherein the search request comprises:
• search criteria defined by a search query from an application;
• and
• a memory capacity threshold of a second memory coupled to the iterator;
• searching, by a processor of the node, for data in the memory matching the search criteria to obtain result data;
• communicating, by the processor, the result data to the iterator;
• pausing communicating the result data to the iterator in view of a pause condition pertaining to the memory capacity threshold of the second memory;
• and
• in response to a resume condition, resuming communicating the result data to the iterator.
