Method Details

init

public void init(InformixOffsetContext offsetContext)

Specified by:

init in interface io.debezium.pipeline.source.spi.StreamingChangeEventSource<InformixPartition,InformixOffsetContext>

execute

public void execute(io.debezium.pipeline.source.spi.ChangeEventSource.ChangeEventSourceContext context,
 InformixPartition partition,
 InformixOffsetContext offsetContext)
             throws InterruptedException

Executes this source. Implementations should regularly check via the given context if they should stop. If that's the case, they should abort their processing and perform any clean-up needed, such as rolling back pending transactions, releasing locks etc.

Specified by:

execute in interface io.debezium.pipeline.source.spi.StreamingChangeEventSource<InformixPartition,InformixOffsetContext>

Parameters:

context - contextual information for this source's execution

Throws:

InterruptedException - in case the snapshot was aborted before completion
