@hardik you probably already know this but the title has a version typo in it (v20.11.0 vs v21.03.0)

It looks like you guys killed it on this update… docs are already up-to-date, almost 30 changes! Nice! What is the ETA for Dgraph Cloud?

Thanks,

When I run wget https://github.com/dgraph-io/dgraph/raw/master/contrib/config/docker/docker-compose.yml && docker-compose up I’m seeing:

alpha_1 | Dgraph version : v20.11.0
alpha_1 | Dgraph codename : tchalla

Does it need to be updated?

#8

What is up with the dropping Schema Versioning and History and how will this change things?

#9

We were trying to store GraphQL schema history within Dgraph. It was complex and largely unused. So, we decided to remove that. Typically, schema versioning is something users would handle on their own.

If Dgraph Cloud users ask for this, this feature can be achieved from within the Cloud infrastructure.

#10

I agree better versioned in the clients control. The backups have the schema though so restoring a backup would also include the schema at that point in time. #removeComplexity #makeRoomForBiggerThingsToCome

Forgot to add that Ratel was removed everywhere. Why? What the real reason?

It was not production but testing\debugging ready tool. Now it’s complicated to run itself in all deployments and containers. Now it’s make fast-start work with dgraph more complicated

#12

Hello @1Const1 , we wanted to simplify the Dgraph package and only group needed binaries in the release.
For the purpose of your usecase there are few ways you can still use Ratel easily

  1. Leverage https://play.dgraph.io/ which contains all the latest features in Ratel needed for 21.03.
  2. Build the binary using the script Ratel Build Instructions
  3. We would also be generating a Ratel binary on Ratel github repository for 21.03 which could be downloaded
#13

I spun up Dgraph Cloud instance May 15, 2021 ($10/month shared plan) and it’s on v20.11.2. Any idea on timeline?

I’m really looking forward to standard claims and upserts!

#14

They are a month behind on the Cloud ETA:

I would think new instances would be one of the first things they do since upgrading is a different process… I’m sure they’ve been concentrating on the upgrade process.
