Method drop_partition

nodedb-graph/src/sharded.rs:93–95

Drop a tenant's entire graph state. Returns `true` if a partition existed and was removed, `false` if the tenant had no graph state. Used by tenant-purge flows — O(1) structural deletion replaces the former "range-scan and erase every key with the `{tid}:` prefix" approach, which was both slow and coupled to the lexical encoding.

        self.partitions.remove(&tid).is_some()
    }
