LruBlockCache.BlockBucket (Apache HBase 1.2.12 API)

java.lang.Object
- org.apache.hadoop.hbase.io.hfile.LruBlockCache.BlockBucket

All Implemented Interfaces:

Comparable<LruBlockCache.BlockBucket>

Enclosing class:

LruBlockCache
```
private class LruBlockCache.BlockBucket
extends Object
implements Comparable<LruBlockCache.BlockBucket>
```
Used to group blocks into priority buckets. There will be a BlockBucket for each priority (single, multi, memory). Once bucketed, the eviction algorithm takes the appropriate number of elements out of each according to configuration parameters and their relatives sizes.
