Receiving multiple Input from Web portal. #616

Open XiaoKuge opened 3 months ago

XiaoKuge commented 3 months ago

Is your feature request related to a problem? Please describe. We are developing a Web frontend that drives dora-flows at the backend. It seems that we can only setup a dynamic node at the begining of the dora flow to get input. The middle nodes won't be able to take the additional input.

Describe the solution you'd like Provide the middle-nodes capability to receive input from frontend.

Describe alternatives you've considered N/A

Additional context

Thank you!

I'm not sure, I understand. Could you provide a simple example ?

haixuanTao commented 3 months ago

I think that you might have been blocked by: https://github.com/dora-rs/dora/pull/606 not being merged.

Now that it's merged it should be easier to have receive-only dynamic node

How should I use this configuration? Could you provide an example of how to configure synchronized_start in YAML or Python?

haixuanTao commented 3 months ago

Do you need that all nodes are ready to start or do you want them to start independently from your web front end?

I want them to start independently from the web front end.

haixuanTao commented 3 months ago

Yes, so you don't need to configure anything the new merged PR will allow you to do just that.

Yes, so you don't need to configure anything the new merged PR will allow you to do just that.

However, have you tried including multiple dynamic nodes in a dataflow? When I started one of the nodes, there was no response at all.

Can you take a look at this issue?

haixuanTao commented 3 months ago

Yes, with the latest version that I have just merged. You can include multiple dynamic nodes. You can even include them in the same python script.

How should I get your updates? Should I reinstall Dora-RS? If so, which version should I install?

haixuanTao commented 3 months ago

Yes so, to update to latest main:

sudo rm $(which dora)
pip uninstall dora-rs

## dora binary
git clone https://github.com/dora-rs/dora.git
cd dora
cargo build --release -p dora-cli
PATH=$PATH:$(pwd)/target/release

## Python API
maturin develop -m apis/python/node/Cargo.toml
