Struct CollectionArenaRegistry 

pub struct CollectionArenaRegistry { /* private fields */ }

Registry of per-collection jemalloc arenas.

Wrap in Arc to share between the Data Plane (writes) and the Control Plane (stats reads). Internal locking is handled by the registry itself.

Implementations

impl CollectionArenaRegistry

pub fn new() -> Arc<Self>

Create a new empty registry wrapped in Arc.

pub fn get_or_create( &self, tenant_id: u64, collection: &str, ) -> Result<CollectionArenaHandle>

Return (or create) a dedicated arena for (tenant_id, collection).

Idempotent: calling twice with the same key returns the same handle.

pub fn get( &self, tenant_id: u64, collection: &str, ) -> Option<CollectionArenaHandle>

Look up an existing handle without creating one. Returns None when the collection has no dedicated arena yet.
