David Fetter recounts:
As has long been my wont, in about May of 2006, I was looking around for
something cool to do in PostgreSQL that no one had done before. I figured
perl6 would make a great PL, but there was no implementation at the time, or at
least nothing that looked like it might become embeddable Parrot, despite its
long ride on the fail whale, looked like the most promising way for the long
term, So i came up with a couple of designs inspired by the PL/Java and PL/J
projects. PL/Java produced working code, although to this day I'm not sure
that it's production quality. It did this by instantiating a jvm in each
connection. PL/J's design was in some sense more elegant, but it never got
anywhere. In PL/J, there was to be some kind of IPC to a java "server." The
problem is that IPC and little servers are extremely difficult to get right, so
for now, I'm thinking that the PL/Java model has more JFDI.
Jonathan "Duke" Leto adds:
I started hacking on PL/Parrot in October of 2009 and it started to actually work
in April 2010.
