方法详细资料

generateXid

Xid generateXid(org.apache.seatunnel.api.common.JobContext context,
                org.apache.seatunnel.api.sink.SinkWriter.Context sinkContext,
                long checkpointId)

open

default void open()

belongsToSubtask

boolean belongsToSubtask(Xid xid,
                         org.apache.seatunnel.api.common.JobContext context,
                         org.apache.seatunnel.api.sink.SinkWriter.Context sinkContext)

返回:

true if the provided transaction belongs to this subtask

close

default void close()

指定者:

close 在接口中 AutoCloseable

semanticXidGenerator

static XidGenerator semanticXidGenerator()

Creates a XidGenerator that generates xids from:

1. job id
2. subtask index
3. checkpoint id
4. four random bytes generated using SecureRandom)

Each created XidGenerator instance MUST be used for only one Sink instance (otherwise Xids could collide).
