Tell us about your request Support configurable swap for Fargate containers & tasks. Use cases are similar to #322. (Note there are a number of requests in that issue for Fargate swap support.)
Which service(s) is this request for? Fargate
Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard? I have a long-running container with one periodically-run process that requires substantially more memory than other processes. I don't care about CPU performance for this process. So it is an ideal candidate for swap.
Are you currently working around this issue? By running the Fargate task configured with the worst-case memory requirement. Before addition of the memory-intensive process, I could run with container memory = 1024. Now, due to this one periodic process, I must run with container memory = 3072. Doing so consumes more memory resources (and associated expense) than is necessary.
Additional context According to the documentation:
The swap space container definition parameters are only supported for task definitions that specify the EC2 launch type. These parameters are not supported for task definitions intended only for Amazon ECS on Fargate use.
