Examples with DataOperator cz.o2.proxima.repository.DataOperator used on opensource projects

Example 1 with DataOperator

use of cz.o2.proxima.repository.DataOperator in project proxima-platform by O2-Czech-Republic.

the class ReplicationController method runTransform.

private void runTransform(String name, TransformationDescriptor transform, DirectAttributeFamilyDescriptor family) {
    final StorageFilter filter = transform.getFilter();
    final String consumer = transform.getConsumerNameFactory().apply();
    final CommitLogReader reader = family.getCommitLogReader().orElseThrow(() -> new IllegalStateException("Unable to get reader for family " + family.getDesc().getName() + "."));
    final TransformationObserver observer;
    if (transform.getTransformation().isContextual()) {
        DirectElementWiseTransform transformation = transform.getTransformation().as(DirectElementWiseTransform.class);
        observer = contextualObserver(dataOperator, name, transformation, transform.getOutputTransactionMode() == OutputTransactionMode.ENABLED, filter);
    } else {
        ElementWiseTransformation transformation = transform.getTransformation().asElementWiseTransform();
        observer = nonContextualObserver(dataOperator, name, transformation, transform.getOutputTransactionMode() == OutputTransactionMode.ENABLED, filter);
    }
    startTransformationObserverUsing(consumer, reader, observer);
    log.info("Started transformer {} reading from {} using {}", consumer, reader.getUri(), transform.getTransformation().getClass());
}
