    We don't recommend ever using ThreadLocal for processors in NiFi. This is because each time a Processor is run, it is done in a potentially different thread. For a large deployment you could have hundreds of threads, and the threads stay around for the life of the instance, so the cleanup is a little awkward. The pattern that we commonly follow is to use a BlockingQueue and poll from that, then create if necessary, and put back. I.e., a simple Object Pool. And I did consider it but decided that the complexity that it adds to the code was not worth it, given the cost of creating the DateFormat.

    Fair enough - pushed another commit to do this.

    nit: maybe we can read this in the `onScheduled` method

    nit: what about creating a `ThreadLocal` global variable for this, in order to avoid creating one instance for each item?
