> The memory usage of Streams is currently unbounded in part because of RocksDB, which consumes memory on a per-instance basis. Each instance (ie each persistent state store) will have its own write buffer, index blocks, and block cache. The size of these can be configured individually, but there is currently no way for a Streams app to limit the total memory available across instances.
