Hello Raphael,


Thanks for your fast response. They are really helpful.


We have worked a daily 5000 order lines, 30000 moves project before with another company in V7. After several months, we had terrible performance issues as well. Especially in stock moves and procurements. 


As you mentioned on V8 stock scalability issue is gone. I doubt that still. The new stock level is calculated based on the stock quant history, which will be millions of lines in our case. And what’s more, each stock operation needs to operate on stock quant objects (aplication level + database level), besides the old objects in V7.

Personally I think we need an archive function to save old stock data in another table, redefine the stock level function based on the archive result (inventory line or another seperate table).


For the workflow, I do not know how to deal with it yet. Maybe we should get rid of workflow on each stock operations.


With the volume increases, it requires the system to lighten the resource of every operations . 

It would be great to have a proof that odoo / openerp can work  on that level volume.

Look forward to receiving more feedbacks from the community.


BR,

Hello Lin,

we worked indirectly on a case in the USA with 1/10 of the numbers you mentioned. And we had terrible issues. Just to be clear we were called as firemen and didn't had a chance to study things upfront on that project. Well basically, 2 things became extremely slow: workflows because tables were huge and stock moves (that was on 6.1) because millions of move to crawl to compute any stock level.

On v8, there is good hope that the stock scalability issue is gone. As for the workflows I'm afraid I'll probably still have issues: all workflows use the same tables and open workflow instances of sale, stock, account accumulate. My advice is: if it's on a version prior to v8, forget it because of the way the stock moves work. If it's on v8, well in any case plan some very serious optimizations and testing to see feasibility.

Number of concurrent users isn't too hard to tackle by adding more cores now that we have process based parallelism, but as for very large tables, well you'll have to clean them up often, you'll have tweak indexes, probably to bypass some computations and use some custom SQL, add caching...
I never heard about sharding in OpenERP/Odoo so I guess nobody ever did sharding, so don't assume it would be easy like in frameworks where it's being done...

As for the company we worked for, well, after 18 months they ended up dropping OpenERP for SAP. Probably putting way more money on it than trying again on v8 and paying a lot of engineering to get the things optimized, but still it's the decision they took and scalability was one of the main reasons and that was 1/10th of the figures you mentioned. So don't take that challenge lightly and good luck!

Regards.

Hello Community,


We have a potential lead which has a volume of daily 20000 sale orders and 50000 sale order lines from Magento, which will probably result in a daily 100000 or 200000 stock moves, 3000000 stock moves per month.

I would like to ask that has anyone experience on Odoo/OpenERP with that daily volume? How about the performance after one month?


I would like also to ask if you have any module on 

* archive stock move , sales order, and other objects

* sales forecasting


BR,
