Method Details

start

public void start(MySqlPartition partition)

Description copied from interface: Reader

Start the reader and return immediately. Once started, the SourceRecords generated by the reader can be obtained by periodically calling Reader.poll() until that method returns null.

This method does nothing if it is already running.

Specified by:

start in interface Reader

Overrides:

start in class BlockingReader

poll

public List<org.apache.kafka.connect.source.SourceRecord> poll()
                                                        throws InterruptedException

Description copied from class: BlockingReader

Does nothing until the connector task is shut down, but regularly returns control back to Connect in order for being paused if requested.

Specified by:

poll in interface Reader

Overrides:

poll in class BlockingReader

Returns:

the list of source records that may or may not be empty; or null when there will be no more records because the reader has completely Reader.State.STOPPED.

Throws:

InterruptedException - if this thread is interrupted while waiting for more records
