Well Lars, looks like that hypoxia has set in… If you’ve paid attention, its not that I’m against server side extensibility.
Its how its been implemented which is a bit brain dead. I suggest you think more about why having end user code running in the same JVM as the RS is not a good thing. (Which is why in Feb. Andrew made a patch that allowed one to turn off the coprocessor function completely or after the system coprocessors loaded. ) The sad truth is that you could have run the coprocessor code in a separate JVM. You have to remember coprocessors are triggers, stored procedures and extensibility all rolled in to one. As to providing a patch… will you indemnify me if I get sued? ;-) Didn’t think so. > On Apr 9, 2015, at 10:13 PM, lars hofhansl <la...@apache.org> wrote: > >> if you lecture people and call them stupid (as you did in an earlier email) > He said (quote) "committers are suffering from rectal induced hypoxia", we > can let that pass as "stupid", I think. :)Maybe Michael can explain some day > what "rectal induced hypoxia" is.
