Method get_or_create

nodedb-graph/src/sharded.rs:82–84

Mutable access to a tenant's partition, creating an empty one on first use. This is the canonical write-path entry point: insertion handlers call this once to resolve the partition, then operate on the returned `&mut CsrIndex` exactly as they would on a standalone instance.

(&mut self, tid: TenantId)

    /// returned `&mut CsrIndex` exactly as they would on a standalone
    /// instance.
    pub fn get_or_create(&mut self, tid: TenantId) -> &mut CsrIndex {
        self.partitions.entry(tid).or_default()
    }

    /// Drop a tenant's entire graph state.
