This release contains 1 new feature and 1 bug fix.

🆕 Features

Flows now compatible with DocArray v2 (#5861)

Finally, Flows and Deployments are fully compatible with the new DocArray version (above 0.30.0). This includes all supported protocols and features, namely http, grpc and websocket for Flow and http and grpc for Deployment.

Now you can enjoy the capacity and expressivity of the new DocArray together with the performance, scalability and richness of Jina.

from docarray import BaseDoc, DocList
from jina import Flow, Executor, requests

class MyDoc(BaseDoc):
    text: str

class MyExec(Executor):
    @requests(on='/foo')
    def foo(self, docs: DocList[MyDoc], **kwargs):
        docs[0].text = 'hello world'

ports=[12345, 12346]
protocols=['http, 'grpc']
with Flow(protocol=protocols, ports=ports).add(uses=MyExec):
    for port, protocol in zip(ports, protocols):
        c = Client(port=port, protocol=protocol)
        docs = c.post(on='/foo', inputs=MyDoc(text='hello'), return_type=DocList[MyDoc])
        assert docs[0].text == 'hello world'

While Jina is fully compatible with the new DocArray version, for now it will not install the latest version, since there remain compatibility issues with Hubble and JCloud. As soon as these are resolved, Jina will install the new version by default.

🐞 Bug Fixes

Fix instantiation of Executor with write decorator (#5897)

Fix instantiation of Executors where the first method is decorated with a @write decorator.

from jina import Executor, requests
from jina.serve.executors.decorators import write

class WriteExecutor(Executor):
    @write
    @requests(on='/delete')
    def delete(self, **kwargs):
        pass

    @requests(on='/bar')
    @write
    def bar(self, **kwargs):
        pass
