This ist basically my daily work. I have to write Java code in excel files which then are being converted into a DSL and then again being converted into Java code. On top of that many wrappers were built which abstract all this things away..

We have about 30 such excel files which contain about 50000 business rules.
There is no version control for this tables and 5 different team are working on the same tables parallel.

The name of this framework is Drools or as I call it: HELL 😡

How old is drools? Dynamic class loading is a thing for a while now,. Shouldve implemented business rules as plugins instead.

The main problem is the versioning and debugging.. If you have any problem you usually waste hours to find tiny bugs.

Was working on excel dumper for our crud app. The main problem was size, most Excel libs dumps all content to memory so our 16gb server was using half of this to parse single file.

Oh my. We also use Drools but our rules are all written in an expression language called MVEL. It's works ok for our ~200 rules.
