getNextBatch

public CompletableFuture<ConnectorSplitSource.ConnectorSplitBatch> getNextBatch(int maxSize)

Specified by:

getNextBatch in interface ConnectorSplitSource

isFinished

public boolean isFinished()

Description copied from interface: ConnectorSplitSource

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.

isFinished in interface ConnectorSplitSource
