How BLite implements the HNSW algorithm for nearest-neighbor vector search — level assignment, greedy layer traversal, Algorithm 4 neighbor selection, and the .NET specifics that keep it allocation-light.
> Read moreA walkthrough of BLite's B+Tree implementation: page-aligned nodes, struct-based headers, node splitting with ArrayPool, range scans over doubly-linked leaf pages, and the stackalloc trick in the read path.
> Read moreHow BLite uses a Write-Ahead Log to guarantee durability, and the Group Commit pattern — backed by System.Threading.Channels and TaskCompletionSource — that amortizes the cost of fsync across concurrent transactions.
