Hello together,
I have tried to profile my cdk taverna project with a profiling tool but
I failed. Hopefully you can give me a little hint of how to solve this
nasty memory leaks.
But first let me explain how my workers work.
Because I am working with CDK objects they are serialized as a byte
array so that they can be passed via the output port to another worker.
In the receiving workers the bytes are deserialized to CDK objects. Here
is a code snippet how the serialization and the port configuration is done:
Configuring the output port:
T2Reference containerRef = referenceService.register(dataList, 1,
true, context);
outputs.put(this.RESULT_PORTS[0], containerRef);
the datalist is a list containing byte arrays (the serialized objects,
List<byte[]> dataList)
Getting the data from the input port:
List<byte[]> dataList = (List<byte[]>)
referenceService.renderIdentifier(inputs.get(this.INPUT_PORTS[0]),
byte[].class, context);
the dataList is in the end deserialized to the CDK objects.
Additionally I am using an looped workflow which is executed several
hundred times to iterate over a big sdfile library.
Is there a need to deregister the registered objects
(referenceService.register(dataList, 1, true, context)) or does Taverna
itself discard them if they are not needed anymore?
Any hint what is running wrong is desired.
Regards,
Andreas
