* Try Ristretto cache * Tweak * It's beautiful * Update GMSL * More strict keyable interface * Fix that some more * Make less panicky * Don't enforce mutability checks for now * Determine mutability using deep equality * Tweaks * Namespace keys * Make federation caches mutable * Update cost estimation, add metric * Update GMSL * Estimate cost for metrics better * Reduce counters a bit * Try caching events * Some guards * Try again * Try this * Use separate caches for hopefully better hash distribution * Fix bug with admitting events into cache * Try to fix bugs * Check nil * Try that again * Preserve order jeezo this is messy * thanks VS Code for doing exactly the wrong thing * Try this again * Be more specific * aaaaargh * One more time * That might be better * Stronger sorting * Cache expiries, async publishing of EDUs * Put it back * Use a shared cache again * Cost estimation fixes * Update ristretto * Reduce counters a bit * Clean up a bit * Update GMSL * 1GB * Configurable cache sizees * Tweaks * Add `config.DataUnit` for specifying friendly cache sizes * Various tweaks * Update GMSL * Add back some lazy loading caching * Include key in cost * Include key in cost * Tweak max age handling, config key name * Only register prometheus metrics if requested * Review comments @S7evinK * Don't return errors when creating caches (it is better just to crash since otherwise we'll `nil`-pointer exception everywhere) * Review comments * Update sample configs * Update GHA Workflow * Update Complement images to Go 1.18 * Remove the cache test from the federation API as we no longer guarantee immediate cache admission * Don't check the caches in the renewal test * Possibly fix the upgrade tests * Update to matrix-org/gomatrixserverlib#322 * Update documentation to refer to Go 1.18
