Multi-Part MPP send support about joule-extension

[wbobeirne]

Unfortunately this API is only accessible over gRPC via SendPayment, but looks like the work isn't backported to SendPaymentSync which is what the REST API uses. Joule is limited to the REST API since it runs in the browser, which has no way to communicate over gRPC.

Marking this as blocked, would love to implement it if #8 ever gets done, but it's a huge shift in the way Joule works.

As an aside, I think the best UX is likely one where the user doesn't need to concern themselves with how many paths their payment takes. If we can't find a route with a single payment, try two. If it can't find one with two, try three etc.

Ok I understand, it would be a big refactoring indeed. Another solution would be to set the default value in LND directly, it would automatically allow MPP in Joule.

About the UX: LND does that automatically already :) you just need to tell him when it should stop trying to split the payment with this parameter. So I think we agree that it should be a general setting in a menu.

Setting the default value in LND looks finally much better for UX. It may be a good idea to allow this setting in later LND realeases.

I close the issue as a solution from LND seems much easier and better, thanks again for this amazing app 👍
