Could you build this?
No Building a custom B+Tree database engine with sub-second distributed consensus and replication across 100+ nodes requires expert-level distributed systems and low-level storage engineering.
What it would actually take: The architecture involves a low-level systems language (C++, Rust, or Go) implementing an on-disk B+Tree storage manager with write-ahead logging (WAL), buffer pool management, and memory-mapped I/O. The primary challenge is the distributed consensus or replication protocol (such as Raft, Paxos, or tree-based multicast gossip) engineered to achieve sub-second synchronization across 100+ heterogeneous nodes without deadlocks or split-brain. This requires deep systems programming, storage engine design, and formal distributed systems verification.
