# Transactions in the CDM Library - Configuration

## The default propagation strategy for service classes is `Propagation.SUPPORTS` 

With r8688 `Propagation.SUPPORTS` as been set as default propagation strategy for all service classes:

~~~

@Transactional(readOnly = true, propagation = Propagation.SUPPORTS) 

class ...

~~~

This has been only introduced to prevent early commit in Spring Web-flow.

In Forums and blocks the recommendation to set the propagation strategy to Propagation.SUPPORTS, this should increase the performance:

* http://forum.springsource.org/showthread.php?61190-Propagation-Support-readOnly-true-vs-no-transactin-at-all

We tested the effect of setting propagation strategy to `Propagation.SUPPORTS` and could not find a significant difference.
