Constructor Detail

CassandraStreamReader

public CassandraStreamReader(StreamMessageHeader header,
                             CassandraStreamHeader streamHeader,
                             StreamSession session)

Method Detail

read

public SSTableMultiWriter read(DataInputPlus inputPlus)
                        throws java.io.IOException

Specified by:

read in interface IStreamReader

Parameters:

inputPlus - where this reads data from

Returns:

SSTable transferred

Throws:

java.io.IOException - if reading the remote sstable fails. Will throw an RTE if local write fails.

getHeader

protected SerializationHeader getHeader(TableMetadata metadata)
                                 throws UnknownColumnException

Throws:

UnknownColumnException

createWriter

protected SSTableMultiWriter createWriter(ColumnFamilyStore cfs,
                                          long totalSize,
                                          long repairedAt,
                                          java.util.UUID pendingRepair,
                                          SSTableFormat.Type format)
                                   throws java.io.IOException

Throws:

java.io.IOException

totalSize

protected long totalSize()

writePartition

protected void writePartition(CassandraStreamReader.StreamDeserializer deserializer,
                              SSTableMultiWriter writer)
                       throws java.io.IOException

Throws:
