@InterfaceAudience.Private public class ArraySearcherPool extends Object
Pools PrefixTreeArraySearcher objects. Each Searcher can consist of hundreds or thousands of objects and 1 is needed for each HFile during a Get operation. With tens of thousands of Gets/second, reusing these searchers may save a lot of young gen collections.
Alternative implementation would be a ByteBufferSearcherPool (not implemented yet).| Modifier and Type | Field and Description |
