Reference for the OpenDigger ClickHouse database schema (database `opensource`). Use this skill when writing, reviewing, or debugging SQL against the OpenDigger backend store — e.g. querying the `events` table, OpenRank/contribution rankings (`global_openrank`, `community_openrank`, `normalized_community_openrank`), repo/user metadata (`repo_info`, `user_info`), labels, location data, or AI analysis tables (`issue_info`, `pull_info`). It explains every core table's purpose, engine, sort/partition keys, key columns, the materialized views, and how the tables relate, so you can write correct, performant ClickHouse queries.
