Hello All, I know that this may sound totally absurd but I am trying to achieve an asynchronous mechanism between my 2 APIs - GET and POST. A quick lookup as follows in the image -
Steps: 1. Python client script calls a GET getObject() API available with Java server with 2 params - bucket name and object key 2. Jetty server performs gets the real object from my custom S3 object server (on-prem) 3. Jetty server also gets the lambda function name that is available in a Redis instance for the bucket name 4. Jetty server now forwards the request to a Python Flask server which has the lambda function by passing object data to it 5. Lambda function code perform the transformation on the object and POST it back to Jetty server (which is a different API called writeGetObjectResponse) 6. WriteGetObjectResponse should now send response to the original caller (python client) where I am stuck at Basically, I am trying to develop my own S3 Object Lambda and reproduce what AWS has done using a simpler way. I am not sure if this is the right approach but AWS does this in the exact same way where s3.getObject() get the reply from s3.writeGetObjectResponse(). To make this work, I am trying to find something using which I would be able to map the request with some unique identifier and as soon as I get transformed data back in writeGetObjectResponse(), my jetty server will send the response back to the original client. I tried using getSession().getId() but seems like that is null for httpservletrequest. Any idea how can I identify each GET request with unique identifier? And also can I reply to a request the way I am willing to do? Please help. Best, Aniruddha ======== ᐧ
