sguo / DirectMemory

DirectMemory is a cache implementation featuring off-heap memory storage (a-la BigMemory) to enable caching of large (or large numbers of) objects without degrading jvm performance. Its main purpose is to act as a second level cache (after a heap based one) to collect large amounts of data without filling up the java heap and thus avoiding long garbage collection cycles. Included in the box is a small set of utility classes to easily handle off-heap memory buffers
