Struct NotificationRef 

pub struct NotificationRef {
    pub sequence: u64,
    pub source_id: u32,
    pub event_type: EventType,
    pub row_count: u32,
    pub timestamp: i64,
    pub batch_offset: u64,
    /* private fields */
}

Zero-allocation notification reference for Ring 0.

Exactly 64 bytes (#[repr(C, align(64))]) to occupy a single cache line, avoiding false sharing when used in lock-free notification slots.

Contains only metadata — actual data is fetched from Ring 1 using batch_offset as a reference into a shared buffer.

Fields

sequence: u64

Monotonically increasing sequence number.

source_id: u32

Identifier of the source materialized view or query.

event_type: EventType

The type of change event.

row_count: u32

Number of rows affected.

timestamp: i64

Event timestamp (milliseconds since epoch).

batch_offset: u64

Offset into a shared batch buffer for data retrieval.
