* [Data Buckets] Zone-Based Data Bucket Caching # Notes - Adds a data bucket cache so we're not needlessly hitting the database every time we need to read a data bucket value. * Cleanup and unify GetData access patterns * Cache work * Push * Add to cache when we fetch and do a db hit * Handle bucket misses in cache * Formatting * Logging * [Data Buckets] Zone-Based Data Bucket Caching - Adds a data bucket cache so we're not needlessly hitting the database every time we need to read a data bucket value. * Cleanup and unify GetData access patterns * Cache work * Push * Add to cache when we fetch and do a db hit * Handle bucket misses in cache * Formatting * Remove redundant fetches from cache since GetData does the same thing * Push progress * Distributed cache work * Logging * Fix issue with scoping where same named keys could return overlapping results * Misses cache tweak, logging, comments * Add bot, client, and NPC bucket methods to Lua. --------- Co-authored-by: Akkadius <akkadius1@gmail.com>
