| Class and Description |
|---|
| BlockWorker
A block worker in the Alluxio system.
|
| Class and Description |
|---|
| AbstractBlockStoreEventListener
A block store event listener base class implementing the
BlockStoreEventListener
interface with empty methods bodies. |
| BlockHeartbeatReport
Container for the delta information in each worker-to-master heartbeat.
|
| BlockLockType
A read-write lock to guard one block.
|
| BlockMasterClient
A wrapper for the gRPC client to interact with the block master, used by alluxio worker.
|
| BlockMetadataManager
Manages the metadata of all blocks in managed space.
|
| BlockMetadataView
This class is an abstract class for allocators and evictors to extend to provide
limited access to block metadata.
|
| BlockStore
A blob store interface to represent the local storage managing and serving all the blocks in the
local storage.
|
| BlockStoreEventListener
A listener interface for receiving metadata mutation events of
BlockStore. |
| BlockStoreLocation
Where to store a block within a block store.
|
| BlockStoreMeta
Interface for the block store meta in Alluxio.
|
| BlockWorker
A block worker in the Alluxio system.
|
| UfsInputStreamManager
An under filesystem input stream manager that can cache seekable input streams for future reuse.
|
| UnderFileSystemBlockReader
This class implements a
BlockReader to read a block directly from UFS, and
optionally cache the block to the Alluxio worker if the whole block it is read. |
| Class and Description |
|---|
| BlockMetadataView
This class is an abstract class for allocators and evictors to extend to provide
limited access to block metadata.
|
| BlockStoreLocation
Where to store a block within a block store.
|
| Class and Description |
|---|
| AbstractBlockStoreEventListener
A block store event listener base class implementing the
BlockStoreEventListener
interface with empty methods bodies. |
| BlockMetadataEvictorView
This class exposes a narrower view of
BlockMetadataManager to Evictors,
filtering out un-evictable blocks and un-allocatable space internally, so that evictors and
allocators can be developed with much simpler logic, without worrying about various constraints,
e.g. |
| BlockStoreEventListener
A listener interface for receiving metadata mutation events of
BlockStore. |
| BlockStoreLocation
Where to store a block within a block store.
