I'm doing a project using dynamoDB TTL feature to do scheduled tasks. the scheme came most from this article series: https://theburningmonk.com/2019/03/dynamodb-ttl-as-an-ad-hoc-scheduling-mechanism/ So I created a dynamoDB table called "scheduledTasks" , and a lambda function called "stepScheduler" which will be triggered by dynamoDB stream events. In any case, during testing my lambda functions, I made some mistake on my client-side (in this case, android java app) code, so to clean things up, I deleted all entries in my dynamoDB table, but I noticed from my cloudwatch logs that even when my dynamoDB table is empty, the dynamoDB stream is constantly firing off INSERT and REMOVE events at nearly once per minute rate. There are just phantom events since I have zero items in my dynamoDB table. Any help on pinpointing why this is happening is greatly appreciated!.
