Hello, this is Niloy here. I have a 'Hobby' package and am running my microservices here for one and a half months. My first month's bill was $36+, and the second month's estimated bill is moving around $36-$58, which is quite stressful for me. I saw that the majority of my cost was caused by Memory usage. I can't limit my RAM to less than 500MB using UI, though nearly 15 services require less than 200 MB. I used the 'RAILWAY_MEMORY_LIMIT' environment variable to cut the memory usage down. But I don't think they can control it. Is there any better and more reliable way to handle my memory usage properly so that I can maintain a cost (under $30) that I can afford for a longer period? Thanks
