@Guewen, just a note to tell that a per product export is how I implemented https://github.com/akretion/solerp/tree/master/solerp and this is exactly where I use your queue framework.

In fact we already had SolR knowledge and I had the opportunity to follow the SolR Unleashed training, that's why for now. If you like you can join forces now to have something working quick. Later if you convince me Elastic Search is better we port the stuff to Elastic Search. BTW SolR is just as json as ElasticSearch I believe. Now yes, there is 130 Mo, but when you should do bzr branch lp:ocb-addons , this becomes negligible ;-) > I am building a Service Oriented Architecture with : > > webapp > |--> readonly solr or elasticsearch > |--> very little django based rest api for managing baskets, auth and so > on > |--> openerp > My architecture is pretty much similar... Are you allergic to Ruby on Rails? If not I have built some killer open source framework for such architecture... My Django is replaced by Rails in my case and I have terrific layers over the OOOR connector that allows me to edit OpenERP data as if it was a pure Rails app when user needs to interact with the data. Else it's all handled by SolR with rsolr and blacklight, https://github.com/projectblacklight/blacklight, a technology built at Standford university and now powering many other US universities http://projecthydra.org/ Just a word to tell that i my case I have no extra front-end database (except a simple front-end User table managed by Devise https://github.com/plataformatec/devise) like you may have with Prestashop. Aside from being extremely fast, it also has the advantage that there no data duplication like you have in traditional Prestashop or Magento connectors and which create some operational and maintenance cost. Say Apache SolR is just a cache that you can trust 100% to be up to date after 1 or 2 seconds with OpenERP data, else the data is all managed in OpenERP in a normalized way. An other characteristic is because I had no faith OpenERP snapshot isolation SQL would scale easily enough for the size of the website (possibly dozens of thousands of logged users interacting with data, hard to predict yet), I built the framework in such a way that I can shard the data over several independent OpenERP that feed the same SolR bigdata. In my case one OpenERP per city or group of cities (synch'ed by conf management devops then). If you think about a SolR based REST catalog, please contact me as this something I'm highly interested in for the future. > I’ve forked solerp (my github account is gorghoa), and will read it and > evaluate it against my needs very soon. > Cool! I apologize for the current lack of documentation. But you can get an idea on how to use it with this example for synchronizing products: https://github.com/akretion/solerp/blob/master/solerp/product.py You also need to set up the right SolR schema. My philosophy in Solerp has been to be the more generic possible out of the box so OpenERP objects have some reflexive way to map themselves to SoLR fields with a way to denormalize hierachies into a SolR noSQL flat collection: include m2o and denormalize o2m and m2m optionally. That default processing assumes some dynamic fields in your SolR schema such as *_s for strings, *_i for integers... In a real application you typically override the default serialization to add a few extra fields of your own. Regards, let me know how it goes with my connector if you use it.
