I see, thanks for the answers! What about moving all the data to the new Gemstone configuration? Is it possible to materialize Fuel graphs from within Gemstone? 2013/1/29 Paul DeBruicker <pdebruic@gmail.com>
I'm sure the gemstone guys will chime in with more details.
Iliad does not have to run in the GemTools image. No need to get 0.9.1.2 to run in older Pharo versions. You just use the GemTools image as the IDE for Gemstone. So start the GemTools image and connect to the stone and use it to load Iliad 0.9.1.2 into Gemstone by running the Gemstone specific Monticelo or workspace or browsers.

Hi list,
I've heard the "develop in Pharo, deploy in Gemstone" idea a million times, and I'd like to understand how people proceed in real-world cases.
I've done my homework and I've watched and read a lot of beginner tutorials, but I still have lots of pieces missing. Here's our scenario:
We have a web app, built on Pharo 1.4 and Iliad 0.9.1.2. Currently, we handle persistence on the image and we have a scheduler process doing regular Fuel backups every 10 minutes, and we also keep daily backups in case things go wrong.
The app is starting to gain momentum, and it feels like things are going to start being way too sluggish soon, so we need to scale.
We've been trying many different persistence approaches, but we'd love to stay inside Smalltalk. We hate having to flatten and pump back our objects all the time. Also, REST apis to any kind of DB are not good enough for us, every o(n) operation becomes unbearably slow, as n REST calls must be sent out and n answers received.
In short, we want to use Gemstone, as we've read it's best for complex, intertwined Smalltalk models, and it scales like crazy.
We'd be okay with Pharo being the "dealer" between clients and the DB, but as I understand, GemTools can't be installed on Pharo 1.4, so we're kind of stuck with an old Pharo 1.1.1 image, in which Iliad 0.9.1.2 can't be installed.
What's the solution here? How does one proceed to migrate an app of this kind? We've developed in Pharo, now how does one accomplish the "deploy in Gemstone" part?
Any pointers to documentation, blog posts or whatever will be so much appreciated.
Thanks a lot in advance,
Bernat.
