PerSSTableIndexWriter

public PerSSTableIndexWriter(AbstractType<?> keyValidator,
 Descriptor descriptor,
 OperationType source,
 Map<ColumnMetadata,ColumnIndex> supportedIndexes)

Method Details

begin

public void begin()

Description copied from interface: SSTableFlushObserver

Called before writing any data to the sstable.

Specified by:

begin in interface SSTableFlushObserver

startPartition

public void startPartition(DecoratedKey key,
 long keyPosition,
 long KeyPositionForSASI)

Description copied from interface: SSTableFlushObserver

Called when a new partition in being written to the sstable, but before any cells are processed (see SSTableFlushObserver.nextUnfilteredCluster(Unfiltered)).

Specified by:

startPartition in interface SSTableFlushObserver

Parameters:

key - the key being appended to SSTable.

keyPosition - the position of the key in the SSTable data file

KeyPositionForSASI - SSTable format specific key position for storage attached indexes, it can be in data file or in some index file. It is the same position as returned by KeyReader.keyPositionForSecondaryIndex() for the same format, and the same position as expected by SSTableReader.keyAtPositionFromSecondaryIndex(long).

staticRow

public void staticRow(Row staticRow)

Description copied from interface: SSTableFlushObserver

Called when a static row is being written to the sstable. If static columns are present in the table, it is called after SSTableFlushObserver.startPartition(DecoratedKey, long, long) and before any calls to SSTableFlushObserver.nextUnfilteredCluster(Unfiltered).

Specified by:

staticRow in interface SSTableFlushObserver

Parameters:

staticRow - static row appended to the sstable, can be empty, may not be null

nextUnfilteredCluster

public void nextUnfilteredCluster(Unfiltered unfiltered)

Description copied from interface: SSTableFlushObserver

Called after an unfiltered is written to the sstable. Will be preceded by a call to SSTableFlushObserver.startPartition(DecoratedKey, long, long), and the unfiltered should be assumed to belong to that partition.

Specified by:

nextUnfilteredCluster in interface SSTableFlushObserver

Parameters:

unfiltered - the unfiltered being written to the SSTable

complete

public void complete()

Description copied from interface: SSTableFlushObserver

Called when all data is written to the file and it's ready to be finished up.

Specified by:

complete in interface SSTableFlushObserver

getIndex

public PerSSTableIndexWriter.Index getIndex(ColumnMetadata columnDef)

getDescriptor

public Descriptor getDescriptor()

newIndex

protected PerSSTableIndexWriter.Index newIndex(ColumnIndex columnIndex)

maxMemorySize

protected long maxMemorySize(ColumnIndex columnIndex)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object
