1. A system for storing data in memory:
- at least one multistage application configured to generate intermediate data in a generating stage of the application and consume the intermediate data in a subsequent consuming stage of the application;
a runtime profiler configured to monitor the application'"'"'s execution and dynamically allocate memory to the application from an in-memory data grid.

Abstract
A method, system and computer program product for storing data in memory. An example system includes at least one multistage application configured to generate intermediate data in a generating stage of the application and consume the intermediate data in a subsequent consuming stage of the application. A runtime profiler is configured to monitor the application'"'"'s execution and dynamically allocate memory to the application from an in-memory data grid.

7. A method for storing data in memory:
-
receiving an estimation of memory required to store intermediate data of a multistage application, the multistage application configured to generate the intermediate data in a generating stage of the application and consume the intermediate data in a subsequent consuming stage of the application; allocating memory from an in-memory data grid before execution of the multistage application based on the estimation of memory required to store the intermediate data of the multistage application; executing the multistage application; monitoring a change in memory required to store the intermediate data during execution of the multistage application; and adjusting the allocated memory at the in-memory data grid based on the change in memory required to store the intermediate data during execution of the multistage application. - View Dependent Claims (8, 9, 10, 11, 12, 13)
