- 方法详细资料
  - getRegionName
```
byte[] getRegionName()
```
    返回:
    
    the region name
  - getStoreCount
```
int getStoreCount()
```
    返回:
    
    the number of stores
  - getStoreFileCount
```
int getStoreFileCount()
```
    返回:
    
    the number of storefiles
  - getStoreFileSize
```
Size getStoreFileSize()
```
    返回:
    
    the total size of the storefiles
  - getMemStoreSize
```
Size getMemStoreSize()
```
    返回:
    
    the memstore size
  - getReadRequestCount
```
long getReadRequestCount()
```
    返回:
    
    the number of read requests made to region
  - getWriteRequestCount
```
long getWriteRequestCount()
```
    返回:
    
    the number of write requests made to region
  - getRequestCount
```
default long getRequestCount()
```
    返回:
    
    the number of write requests and read requests made to region
  - getNameAsString
```
default String getNameAsString()
```
    返回:
    
    the region name as a string
  - getFilteredReadRequestCount
```
long getFilteredReadRequestCount()
```
    返回:
    
    the number of filtered read requests made to region
  - getStoreFileIndexSize
```
Size getStoreFileIndexSize()
```
    TODO: why we pass the same value to different counters? Currently, the value from getStoreFileIndexSize() is same with getStoreFileRootLevelIndexSize() see HRegionServer#createRegionLoad.
    
    返回:
    
    The current total size of root-level indexes for the region
  - getStoreFileRootLevelIndexSize
```
Size getStoreFileRootLevelIndexSize()
```
    返回:
    
    The current total size of root-level indexes for the region
  - getStoreFileUncompressedDataIndexSize
```
Size getStoreFileUncompressedDataIndexSize()
```
    返回:
    
    The total size of all index blocks, not just the root level
  - getBloomFilterSize
```
Size getBloomFilterSize()
```
    返回:
    
    The total size of all Bloom filter blocks, not just loaded into the block cache
  - getCompactingCellCount
```
long getCompactingCellCount()
```
    返回:
    
    the total number of cells in current compaction
  - getCompactedCellCount
```
long getCompactedCellCount()
```
    返回:
    
    the number of already compacted kvs in current compaction
  - getCompletedSequenceId
```
long getCompletedSequenceId()
```
    This does not really belong inside RegionLoad but its being done in the name of expediency.
    
    返回:
    
    the completed sequence Id for the region
  - getStoreSequenceId
```
Map<byte[],Long> getStoreSequenceId()
```
    返回:
    
    completed sequence id per store.
  - getUncompressedStoreFileSize
```
Size getUncompressedStoreFileSize()
```
    返回:
    
    the uncompressed size of the storefiles
  - getDataLocality
```
float getDataLocality()
```
    返回:
    
    the data locality of region in the regionserver.
  - getLastMajorCompactionTimestamp
```
long getLastMajorCompactionTimestamp()
```
    返回:
    
    the timestamp of the oldest hfile for any store of this region.
