public ReplicationStreamBuilder(BaseConnection connection)

Parameters:

connection - not null connection with that will be associate replication

Method Detail

logical

public ChainedLogicalStreamBuilder logical()

Description copied from interface: ChainedStreamBuilder

Create logical replication stream that decode raw wal logs by output plugin to logical form. Default about logical decoding you can see by following link Logical Decoding Concepts .

Example usage:

   RedshiftReplicationStream stream =
        pgConnection
            .getReplicationAPI()
            .replicationStream()
            .logical()
            .withSlotName("test_decoding")
            .withSlotOption("include-xids", false)
            .withSlotOption("skip-empty-xacts", true)
            .start();

    while (true) {
      ByteBuffer buffer = stream.read();
      //process logical changes
    }

   
 

Specified by:

logical in interface ChainedStreamBuilder

Returns:

not null fluent api

physical

public ChainedPhysicalStreamBuilder physical()

Description copied from interface: ChainedStreamBuilder

Create physical replication stream for process wal logs in binary form.

Example usage:

   LogSequenceNumber lsn = getCurrentLSN();

    RedshiftReplicationStream stream =
        pgConnection
            .getReplicationAPI()
            .replicationStream()
            .physical()
            .withStartPosition(lsn)
            .start();

    while (true) {
      ByteBuffer buffer = stream.read();
      //process binary WAL logs
    }
