@UnstableApi +public final class AdaptiveByteBufAllocator +extends AbstractByteBufAllocator +implements ByteBufAllocatorMetricProvider, ByteBufAllocatorMetric+
ByteBufAllocator, that follows an anti-generational hypothesis.
+ + Note: this allocator is experimental. It is recommended to roll out usage slowly, + and to carefully monitor application performance in the process. +
+ See the AdaptivePoolingAllocator class documentation for implementation details.
