I'm a great way to import bigger into an app engine from an older SQL-based application (big table). I'm very confused, though I'm sure I'm missing something simple.
The data is not just a simple spread sheet, it contains customers, appointments and some other things, they are tied together with all the keys, so that a little bit of complexity can be added.
I know that there is a bulk uploader, which seemed more to anyone with administrative access, and I was hoping to come up with a solution that would work for a user.
It seems that if I can upload a file and do this, it will work, but there is a 30-second limit of processes, this is probably 30 seconds time limit if there are some thousand records adding up. Maybe I can use the work queue? I think it may be allowed to take more than 30 seconds, but then I think I have a problem synchronizing with the development server?
It is not that I do not know how to do it, but there is no real way in which there is at least one headache involved.
What I think (and I'm also starting a new one), app engine 'denormalized' data It means that there really is no such thing as 'joins' there are some things that can be connected to the table (I believe connectivity properties) but I do not know how they Work from - I have not tried.
I believe your only option is to convert scripts and rules to convert your SQL data into a denormalized state and then store it in that App Engine. If you have to sync in two ways, then it can be a real quick accelerator!
