MAX_MEMSTORE_TS_KEY

static final byte[] MAX_MEMSTORE_TS_KEY

Max memstore (mvcc) timestamp in FileInfo

方法详细资料

appendFileInfo

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

Add an element to the file info map.

抛出:

IOException

getPath

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

返回:

the path to this HFile

addInlineBlockWriter

void addInlineBlockWriter(InlineBlockWriter bloomWriter)

Adds an inline block writer such as a multi-level block index writer or a compound Bloom filter writer.

appendMetaBlock

void appendMetaBlock(String bloomFilterMetaKey,
                     org.apache.hadoop.io.Writable metaWriter)

addGeneralBloomFilter

void addGeneralBloomFilter(BloomFilterWriter bfw)

Store general Bloom filter in the file. This does not deal with Bloom filter internals but is necessary, since Bloom filters are stored differently in HFile version 1 and version 2.

addDeleteFamilyBloomFilter

void addDeleteFamilyBloomFilter(BloomFilterWriter bfw)
                         throws IOException

Store delete family Bloom filter in the file, which is only supported in HFile V2.

抛出:

IOException

getFileContext

HFileContext getFileContext()

Return the file context for the HFile this writer belongs to
