类 StoreFileWriter

java.lang.Object

org.apache.hadoop.hbase.regionserver.StoreFileWriter

所有已实现的接口:

CellSink, ShipperListener

@InterfaceAudience.Private
public class StoreFileWriter
extends Object
implements CellSink, ShipperListener

A StoreFile writer. Use this to read/write HBase Store Files. It is package local because it is an implementation detail of the HBase regionserver.

方法详细资料

appendMetadata

public void appendMetadata(long maxSequenceId,
                           boolean majorCompaction)
                    throws IOException

Writes meta data. Call before close() since its written as meta data to this file.

参数:

maxSequenceId - Maximum sequence id.

majorCompaction - True if this file is product of a major compaction

抛出:

IOException - problem writing to FS

appendMetadata

public void appendMetadata(long maxSequenceId,
                           boolean majorCompaction,
                           long mobCellsCount)
                    throws IOException

Writes meta data. Call before close() since its written as meta data to this file.

参数:

maxSequenceId - Maximum sequence id.

majorCompaction - True if this file is product of a major compaction

mobCellsCount - The number of mob cells.

抛出:

IOException - problem writing to FS

appendTrackedTimestampsToMetadata

public void appendTrackedTimestampsToMetadata()
                                       throws IOException

Add TimestampRange and earliest put timestamp to Metadata

抛出:

IOException

trackTimestamps

public void trackTimestamps(Cell cell)

Record the earlest Put timestamp. If the timeRangeTracker is not set, update TimeRangeTracker to include the timestamp of this key

append

public void append(Cell cell)
            throws IOException

从接口复制的说明: CellSink

Append the given cell

指定者:

append 在接口中 CellSink

参数:

cell - the cell to be added

抛出:

IOException

beforeShipped

public void beforeShipped()
                   throws IOException

从接口复制的说明: ShipperListener

The action that needs to be performed before Shipper.shipped() is performed

指定者:

beforeShipped 在接口中 ShipperListener

抛出:

IOException

getPath

public org.apache.hadoop.fs.Path getPath()

hasGeneralBloom

public boolean hasGeneralBloom()

close

public void close()
           throws IOException

抛出:

appendFileInfo

public void appendFileInfo(byte[] key,
                           byte[] value)
                    throws IOException

抛出:

IOException
