Hi folks! The following two PRs are ready for re-review: 1. #7655: Fixes the current odd behavior + adds missing documentation for "discovery" queries in distributed queries. It also fixes the following two issues: #5260 and #7793. 2. #7712: This is for future-proof support of osquery downgrades. So that osquery doesn't break whenever a new version adds a column family to RocksDB and users need to downgrade osquery.
