Besides using Oracle REST Data Services (ORDS) as the Apex-Listener, I'm using the AutoREST-Feature of ORDS very heavily.
Oracle is actively developing ORDS: There is a new release about every quarter of the year.
Let aside the new features, the overall performance of the product is being improved continuously.
#ThanksODC was the chance for me to invest some time and measure the real gains.
I was first surprised and then impressed by the results...
