Method Detail
-
logical
ChainedLogicalStreamBuilder logical()
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 }
- Returns:
- not null fluent api
-
physical
ChainedPhysicalStreamBuilder physical()
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 }
- Returns:
- not null fluent api
