Abstract
Embodiments of the invention provide a method, system and computer program product for optimized continuous query processing in an in memory data grid (IMDG). In an embodiment of the invention, a method for optimized continuous query processing in an IMDG includes receiving a request to add an object to an IMDG. The method also includes evaluating a continuous query upon the object in order to produce a result. The method yet further includes adding an attribute to the object referencing the continuous query and assigning a value to the attribute of the result. The method even yet further includes inserting the object with the attribute into the IMDG. Finally, the method includes returning the value of the attribute in lieu of repeating an evaluation of the continuous query in response to receiving a request to repeat an evaluation of the continuous query in respect to the object.
