Method Detail

getNextBatch

CompletableFuture<ConnectorSplitSource.ConnectorSplitBatch> getNextBatch(ConnectorPartitionHandle partitionHandle,
                                                                         int maxSize)

rewind

default void rewind(ConnectorPartitionHandle partitionHandle)

close

void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

isFinished

boolean isFinished()

Returns whether any more ConnectorSplit may be produced.

This method should only be called when there has been no invocation of getNextBatch, or result Future of previous getNextBatch is done. Calling this method at other time is not useful because the contract of such an invocation will be inherently racy.
