Lets say there are a couple dataframes that need a matrix multiply that take up about 10gb on a 32gb host. I want to parameterize these manipulations and expose over http. I can only afford to cache 3 sets of them, which means that I can perform 3 concurrent requests. I would like to provide more concurrency than this without reading from disk or storing the data out of process in a separate service which adds complexity.
