Heap, garbage collection, and empty-sensitive object pools

Abstract:

Techniques for managing object pools within computer storage are disclosed. In some embodiments, a runtime environment determines, for a respective object pool allocated in volatile or non-volatile storage of a computing system, whether a new object has been added to the respective object pool within a threshold timeframe. Responsive to determining that a new object has not been added to the respective object pool within the threshold timeframe, the runtime environment removes a subset of one or more objects from the respective object pool. In some embodiments, the runtime environment monitors a set of one or more garbage collection metrics. Responsive to determining that the set of one or more garbage collection metrics have satisfied one or more thresholds, the runtime environment identifies and removes idle objects from at least one object pool.
