java.lang.Object
org.postgresql.replication.fluent.ReplicationStreamBuilder
All Implemented Interfaces:
ChainedStreamBuilder
public class ReplicationStreamBuilder extends Object implements ChainedStreamBuilder

  • Constructor Details

    • ReplicationStreamBuilder

      public ReplicationStreamBuilder(BaseConnection connection)
      Parameters:
      connection - not null connection with that will be associate replication

  • Method Details

    • 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:

         

    PGReplicationStream 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();

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

    while (true) {
      ByteBuffer buffer = stream.read();
      //process binary WAL logs
    }
      Specified by:
      physical in interface ChainedStreamBuilder
      Returns:
      not null fluent api
