Projects that has used OPA via Java library

Question

Hi All,
Would like to know if OPA been used as a Java library in an actual project/implementation. At the moment I would like to know the approach/strategy and lessons learnt if we go this path - since there is a lot of implementation details to address.
Its a possible integration at the moment for a client of ours - the pros/cons vs OPA as a webservice has been discussed, but due to high performance requirements may need to use OPA as a library. Currently no specific business scenarios for OPA, but the intention is to use it as wide as possible - since any rules not in OPA is likely to be Java.
Cheers
Noel

Answer 1

I know several customers use OPA via the Determinations Engine API. We always recommend using the Determinations Server where possible in preference to the API, as upgrade is generally cleaner and it is generally easier to change the application separately from the policy models.
See also the YouTube video here: http://www.youtube.com/watch?v=9-opkHsAyEI&list=UUtUHPDCD1EFH_ftnhR_i-dQ&index=4&feature=plcp which gives an introduction to the different OPA deployment options available.
