- Add a memory usage NixOS test that provides an overview of metadata-server's memory usage under high load. It doesn't actually "test" anything, only provides statistics.
- Store metadata in the file system instead of a Postgres DB. PR #24 demonstrates that a large user of memory is the Postgres store, specifically building the query for large batch-style requrests. This could be investigated further, but a quick fix is simply to use a file-based store. There is no need to build a query, and files can be looked up quickly using their filename.
