This carries the information on some of the meta data about the HFile.
|
| Class and Description |
|---|
| AgeSnapshot
Snapshot of block cache age in cache.
|
| BlockCache
Block cache interface.
|
| BlockCacheKey
Cache Key for use with implementations of
BlockCache |
| BlockCacheUtil.CachedBlocksByFile
Use one of these to keep a running account of cached blocks by file.
|
| BlockPriority |
| BlockType
Various types of HFile blocks.
|
| BlockType.BlockCategory |
| Cacheable
Cacheable is an interface that allows for an object to be cached.
|
| Cacheable.MemoryType
SHARED means when this Cacheable is read back from cache it refers to the same memory area as
used by the cache for caching it.
|
| CacheableDeserializer
Interface for a deserializer.
|
| CacheConfig
Stores all of the cache objects and configuration for a single HFile.
|
| CachedBlock |
| CacheStats
Class that implements cache metrics.
|
| CombinedBlockCache
CombinedBlockCache is an abstraction layer that combines
LruBlockCache and BucketCache. |
| CombinedBlockCache.CombinedCacheStats |
| CompoundBloomFilterBase |
| CorruptHFileException
This exception is thrown when attempts to read an HFile fail due to corruption or truncation
issues.
|
| FixedFileTrailer
The
HFile has a fixed trailer which contains offsets to other
variable parts of the file. |
| HFile.CachingBlockReader
An abstraction used by the block index.
|
| HFile.FileInfo
Metadata for this file.
|
| HFile.Reader
An interface used by clients to open and iterate an
HFile. |
| HFile.Writer
API required to write an
HFile |
| HFile.WriterFactory
This variety of ways to construct writers is used throughout the code, and
we want to be able to swap writer implementations.
|
| HFileBlock
Cacheable Blocks of an
HFile version 2 file. |
| HFileContext
This carries the information on some of the meta data about the HFile.
|
| HFileContextBuilder
A builder that helps in building up the HFileContext
|
| HFileDataBlockEncoder
Controls what kind of data block encoding is used.
|
| HFileReaderImpl.HFileScannerImpl |
| HFileScanner
A scanner allows you to position yourself within a HFile and
scan through it.
|
| InlineBlockWriter
A way to write "inline" blocks into an
HFile. |
| LruBlockCache
A block cache implementation that is memory-aware using
HeapSize,
memory-bound using an LRU eviction algorithm, and concurrent: backed by a
ConcurrentHashMap and with a non-blocking eviction thread giving
constant-time LruBlockCache.cacheBlock(org.apache.hadoop.hbase.io.hfile.BlockCacheKey, org.apache.hadoop.hbase.io.hfile.Cacheable, boolean) and LruBlockCache.getBlock(org.apache.hadoop.hbase.io.hfile.BlockCacheKey, boolean, boolean, boolean) operations. |
| LruCachedBlock
Represents an entry in the
LruBlockCache. |
