Yep u just needa write the code in the consumer lambdas to send a sns when it’s done processing

i have a video on using EMR to process data with spark here. check it out: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-a_3Md9nV2Mk.html

becuz we passed in a MessageGroupId (it is either 1 or 2) so there are 2 groups of messages and each group can have max of 10 msgs. technically u should only make the batch size to be 1 so the messages will be processed one by one in each group (7:55 of the video)

@@FelixYu thanks

visibility timeout is the time that the message remains invisible by other consumers (e.g., if it is picked up by consumer1, within the visibility timeout, even thou consumer1 fails to process it, consumer2 cannot pick it up. after the visibility timeout, it becomes visible to other consumers again
