Hi,
thanks for the clear and informative article.
our product is composed by several micro-services. some of them are 'workers' services which are actually a scheduler task (lambda) that runs every minute get request from db, execute it and update the status.
we want to adopt the blue/green deployment, and wonder how to apply it with those workes.
the only option we think of is adding a version column to the request so each deployment version process its own requests.
but in that approach some request may never be completed, if the old version is deleted while some request are not finished yet, they will not be taken by the new 'worker' , since the new worker looks only at request with the new version.
can you suggest solution for that? or a different approach?
