sijie edited a comment on issue #3854: [issue #3767] support go function for pulsar URL: https://github.com/apache/pulsar/pull/3854#issuecomment-474232576 @jerrypeng based on my understanding, the approach taken here is producing an executable binary of go-instance and user function and submit the executable binary as a whole to function worker to execute. This is the approach that aws lambda is taking. In that sense, go-instance is a SDK library. It is different from java and python. people imports the go instance sdk, write a function and call `goInstance.startFunc(functionName)` to start a function in go main function. e.g. ``` func helloworld() { // user define logic. } func main() { goInstance.startFunction(helloworld) } ``` There is an alternative is to use go plugins to loading function dynamically. Ideally we can support both. However most of the go developers prefer static linking as that's how go programs are written. so PIP-32 takes the SDK approach here. based on my understanding from the code, this PR focuses on instance implementation itself to make sure a go function is able to run in localrun mode. Once the instance is ready, support running it from function worker becomes easier.
