Struct FatNode

Source

pub struct FatNode { /* private fields */ }

👎Deprecated:

Unused duplicate memtable; live memtables are lscs::ColumnarMemtable + durable_storage::MvccMemTable. Scheduled for removal (Task 2 consolidation).

Expand description

Fat-node for version chain (Rec 2: Lock-Free Fat-Node Version Chain)

Groups up to 8 version pointers per node, reducing pointer chases from O(v) to O(v/8). Slot pointers occupy 64 bytes = 1 cache line, so scanning all 8 slots costs a single cache-line fetch instead of 8 random chases.

Layout:

count (AtomicU8): number of occupied slots (0..FAT_NODE_SLOTS)
slots: array of AtomicPtr, newest at index count-1
next: pointer to older FatNode
