@km3945 The in_memory configuration prevents paging to disk when set to 1. It forces filters to never leave memory. If the setting is set to 0, then bloomd will page it to disk when needed, meaning it is allowed to be out of memory. In this case, you are creating a filter and it starts in memory, which cannot be disabled.
