Abstract: A method of communicating data in a data grid. The method includes receiving a first search request defined by search criteria of a search query. The method includes communicating the first search request to search for data segments at the first node that match the search criteria. The method includes receiving one or more data segments matching the search criteria. The method includes receiving rebalance information. The method further includes identifying a second node storing rebalance data segments of the plurality of rebalance data segments based on the rebalance information. The method further includes communicating a second search request to search for the rebalance data segments matching the search criteria. The method further includes receiving one or more rebalance data segments matching the search criteria. The method further includes determining search result data using the data segments from the first node and the rebalance data segments from the second node.

Abstract: 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.

Abstract: A node including a memory to store data of the node and a processor coupled to the memory. The processor can receive, from a listener in a data grid system, a filter defined by search criteria of a search query. The processor can also communicate, to the listener, data from the memory that is filtered using the filter. The processor can further identify changes to the filtered data. The processor can further record, into a queue, the changes to the filtered data in the memory after the filtered data is communicated to the listener. The processor can further communicate, to the listener, the queue of changes to the filtered data.

Abstract: A method of communicating data in a node cluster of a data grid is described. The method includes receiving, at a listener of a first node, data from a second node that is filtered using the filter during a search query of a node cluster. The method further includes determining, at the listener, that a third node has joined the node cluster during the search query. The method further includes communicating the filter the third node joining the node cluster in response to the third node joining the cluster.

Abstract: A processing device to receive, from a second node in the data grid system, a first filter. The processing device may detect a failure of a third node of the data grid system. The processing device may determine that the backup data stored at the first node matches the first filter. The processing device may send, to the second node, a duplicate data notification indicating that the backup data comprises, at least in part, first data duplicative to second data communicated to the second node from the third node.

Abstract: A processing device to perform operations comprising receive, from a listener of a second node in a data grid system, a filter defined by search criteria of a search query. The operations can include determine, at the first node, that a third node in the data grid has crashed. The operations can further include iterate over backup data of the third node that is stored at a memory of the first node to determine the backup data that matches the filter. The operations can further include communicate, to the listener, the backup data that matches the filter.
