@stariradeff @markdrew @strombergjo hi there!

hi everyone, just throwing this out there! I am building an app and looking into graph.cool.. I need to rank items using a basic ranking algorithm.. just wondering, other than algolia connection, if there's a good way to sync graph.cool data with my another db that I can use to compute (and cache) rankings? anyone had similar requirements? 🙂

I thought perhaps mutation callbacks might be a good approach, but wanted to ask either way! 😄 thanks guys

perhaps an idea might to use mutation callbacks so that when an 'item' is created, it calls a lambda function that writes it to a DB, from there, I can perform some computation and cache the results.. just thinking out aloud here!

I am new to GraphQL / Lambda!

love the work you guys are doing

Thanks @gdiddadi Using mutation callbacks to sync data to an external system works great. You should make sure to write your syncing code in an idempotent way, meaning that it should be possible to sync the same item twice and not end up with multiple items in your external system.

Ok fantastic, that makes a lot of sense.. thank you @sorenbs!

My pleasure 🙂 Let us know if you run into any issues

@fabiantjoeaon hello! nice to have you join us here at graphcool

@gdiddadi I'm working on similar stuff these days! I use Neo4j as a primary DB to rank content, and Graphcool to render a timeline on what users might generally be interested in. The only problem I have is that mutation callbacks only exist for nodes these days : being able to register a callback for relations (user likes content for example) would be much more powerful. Right now, the lambda function is called each time a user is updated and I have to check if the modification implies something on Neo4j. Hope this kind of help!

That's very interesting. Thank you. It does help!

Hi I started receiving "Subscription timed out - no response from server”. Didin’t experience it before.

sometimes subscriptions work, sometimes they don't

@alex_ye I highlighted you in a different thread where we've seen similar reports, let's try to reproduce this together 🙂

Does anybody have any idea how to solve the following: I have a node

Parent

that has many

child

. Every time I create a

child

I want to set

childNumber

property that auto increments. But

childNumber

will be unique for each

Parent

@brucelane @kimchi 🖖 graphcool welcome!

Hello. I am building a react native app with a Graphcool backend for a school project. This app allows users to book appointments with barbers. I would like to integrate a service where the user gets a text message reminder when booking an appointment. Can anyone give me guidance on this? Where to start? Tutorials? Thank you.

ahoi @aaron nice to have you here! 🎉

heyo!

👋

very slick set of tools you folks are building

cheers, appreciate the love! 🙇

happy to share what I'm working on, etc. I'm not a fit for the backend (I don't think), but happy to share architecture, use case etc

awesome! I’ll PM you

👍

Oh @aaron , I really liked your stories about storytelling! 👍

oh hey!

thanks @hvillain

I had fun sharing that one
