* improvement: use appropriate paths for systemd example * improvement: add a configurable postgres write conn string This adds a new configurable connection string for postgres writes. * improvement: document pg connection_write config * build: upgrade checkout action for github ci * perf: use standard allocator, limit sqlite mmap to 4GB This is an experimental change to see if we can reduce memory usage with large SQLite databases. If successful, we'll do this again and further reduce the database mmap size. This will cause greater use of the page cache, but that is more easily reclaimed by the kernel, and should reduce memory pressure, as well as making it clearer how much memory the application is actually using for connections, subscriptions, etc. * docs: reformatting * docs: allow host header prefix matching, required for Damus compatibility * perf: disable sqlite mmap to reduce memory pressure * perf: switch to jemalloc allocator * docs: helpful ubuntu packages for building * perf: reduce SQLite connection count and idle lifetime On lightly loaded relays, we free up memory faster by letting idle connections be reclaimed in 10 seconds instead of the default 10 minutes. This also sets the minimum to zero connections, instead of always trying to hold one open. --------- Co-authored-by: Petr Kracik <petrkr@petrkr.net> Co-authored-by: Kieran <kieran@harkin.me> Co-authored-by: Greg Heartsfield <scsibug@imap.cc> |
