trigger a function through a HTTP API

Capability to trigger a function through a HTTP API
Without using pulsar-admin.
Goal is to get the output fast and be able to handle high number of calls.
Like AWS Lambda where you can serve website content directly from function output

The CLI tool is always using the HTTP API.
The endpoint is https://pulsar.apache.org/functions-rest-api/#operation/triggerFunction

Setting up the content might be a bit involved though :/ since it requires a multi-part body a so on.

it works thanks

do you know if it can handle a lot of hits?

It creates a producer for each http request. Meant for debugging rather than a fast data path.

@srkukarni would it be possible to add scalability there, the goal would be direct content serve client->api gateway->http_api->function like aws is doing with their combo apigateway+lambda

It should't be too hard. Please open an issue.
We love contributions as well :) I could guide you with this.

I read the PRs regularly and not sure I have the Java skills to contribute at this time.
Maybe later
