If Ignite has an already allocated chunk of memory that is not used by other caches, it will use it. Otherwise, a new chunk will be allocated. Other words, if you create, fill and destroy a cache 100 times, Ignite will not allocate memory 100 times, it will reuse what's already allocated. 3. Is there anyway to reclaim memory from off-heap? > No. Instead, you can set the maximum size of a data region via DataRegionConfiguration.setMaxSize(). Once a data region hits maxSize, Ignite will not allocate more memory for the caches in that region. Stan
