What
Documents the new
restore_access_entities_with_current_grantsRESTORE setting in the BYOB "restore using commands" guide.The previous example used
RESTORE ALL EXCEPT TABLES system.users, system.rolesto work around theACCESS_DENIEDfailure that occurs when a backup's access entities (e.g.default_role) carry more grants than the restoring user can grant. On ClickHouse Cloud 26.4 (build26.4.1.1942+) you can insteadRESTORE ALLwithSETTINGS restore_access_entities_with_current_grants = 1, which clamps restored grants to what the restoring user may grant (same semantics asGRANT CURRENT GRANTS) instead of failing.Details
RESTORE ALL ... SETTINGS restore_access_entities_with_current_grants = 1.26.4.1.1942+) withSELECT version()to check the running version.EXCEPT TABLES system.users, system.rolesform documented as the pre-26.4 fallback.Upstream feature PR: ClickHouse/ClickHouse#98795
Rollout: ClickHouse/data-plane-base-configurations#2084
