Hi Brian,
Thanks for the official take on my speculations.
Standalone compilation is definitely the way to go so I will take a
look at table_functions_engine shortly.
But I have another question: PBXT adds 2 system variables:
pbxt_index_cache_size and pbxt_record_cache_size. For the 4.1 version I
just hacked these in, of course.
Is there any plan to make adding system variables possible from within
an engine plugin?
An alternative would be for an engine to create its own configuration
file (not ideal).
