Trying to figure out what the most efficient way to update multiple nodes at once would be. Say the user changes a value for a parent model and then I want to recalculate a field for each node of a child model (one to many relation).

@sebastien there's currently no built-in way to do updates on many nodes at once

Thanks @nilan for the quick answer! So I guess if I find myself really needing to do this I would have to recursively run multiple mutation queries? I assume that this could be pretty bad in terms of performance, right?

It's something we want to add for sure, but there's no timeline yet - also I'm not sure it'll fit your needs. The

updateAll

mutation that we're thinking of is handy if you need to update all nodes specified by the usual filter syntax with the same update

Thanks! Very good to know about deleteAll & updateAll. Yes, in my case, every node that match the filter would be updated with different values, say the result of running

doSomethingWithOldValue(modifier, oldValues)

then I'd recommend doing multiple mutations in a single GraphQL requests instead

Thanks so much, that makes sense! Now I’ll just have to figure out how to create such multi-mutation request using Apollo for Angular. It seems like Apollo for React has something to compose queries or mutations, but I’m not seeing anything similar for Angular.

Hum I'm actually not sure about a great approach here
