Making the DatumReader/Writers configurable would be a welcome addition.
Ideally, much more of what goes on there could be:
1. configuration driven
2. pre-computed to avoid repeated work during decoding/encoding
We do some of both already. The trick is to do #1 without impacting
performance and #2 requires a bigger overhaul.
If you would like, a contribution including a Clojure related maven module
or two that depends on the Java stuff would be a welcome addition and
allow us to identify compatibility issues as we change the Java library
