方法详细资料

initial

public static StartupOptions initial()

Performs an initial snapshot on the monitored database tables upon first startup, and continue to read the latest binlog.

earliest

public static StartupOptions earliest()

Never to perform snapshot on the monitored database tables upon first startup, just read from the beginning of the binlog. This should be used with care, as it is only valid when the binlog is guaranteed to contain the entire history of the database.

latest

public static StartupOptions latest()

Never to perform snapshot on the monitored database tables upon first startup, just read from the end of the binlog which means only have the changes since the connector was started.

specificOffset

public static StartupOptions specificOffset(String specificOffsetFile,
                                            int specificOffsetPos)

Never to perform snapshot on the monitored database tables upon first startup, and directly read binlog from the specified offset.

timestamp

public static StartupOptions timestamp(long startupTimestampMillis)

Never to perform snapshot on the monitored database tables upon first startup, and directly read binlog from the specified timestamp.

The consumer will traverse the binlog from the beginning and ignore change events whose timestamp is smaller than the specified timestamp.

参数:

startupTimestampMillis - timestamp for the startup offsets, as milliseconds from epoch.

equals

public boolean equals(Object o)
