Class Lsn

  • All Implemented Interfaces:
    Comparable<Lsn>
    public class Lsn
extends Object
implements Comparable<Lsn>
    Copied from Debezium 1.9.8.final without changes due to the NoSuchMethodError, caused by the fact that current Debezium release java version is 11, so we need to compile this file by java 8 compiler. More info. Abstraction of PostgreSQL log sequence number, adapted from LogSequenceNumber.

    Line 32: add NO_STOPPING_LSN

    • Field Detail

      • INVALID_LSN

        public static final Lsn INVALID_LSN
        Zero is used indicate an invalid pointer. Bootstrap skips the first possible WAL segment, initializing the first WAL page at XLOG_SEG_SIZE, so no XLOG record can begin at zero.

      • NO_STOPPING_LSN

        public static final Lsn NO_STOPPING_LSN
        The max lsn for the wal file.
