This all began with a very popular request: “We want to be able to throw an Exception from a flow”. The motivation for this is that it’s fairly common to run into “business errors” (errors not related to the handling and transmission of data but the data itself) which should actually be treated in the same way as a connection or system error (things like the remote endpoint is down).
A high-reliability application (one that has zero tolerance for message loss) not only requires the underlying ESB to be reliable, but that reliability needs to extend to individual connections. If your application uses a transactional transport such as JMS, VM, or DB, reliable messaging is ensured by the built-in support for transactions in the transport. This means, for example, that you can configure a transaction on a JMS inbound endpoint that makes sure messages are only removed from the JMS server when the transaction is committed. By doing this, you ensure that if an error occurs while processing the message, it will still be available for reprocessing.
Currently, Mule relies on plain old java serialization in order to store objects to files or to replicate them through a Mule cluster. That imposes limitations on:
This is a follow up to the last post in which we discussed performance improvements on our XPath functionality obtained from the revamped XPath and XSLT support in Mule 3.6. This time, we’ll go through the same exercise but for the XSLT use case.
Just like with XPath, we worked with Luciano Gandini from the performance team. He came up with a test in which he measures the transactions per second (TPS) and latency of two XSLT transformations which inverts the tags of an XML.
