intermediateMongoDB Schema Design — Embedding vs. Referencing

Why is an unbounded embedded array a real design risk in MongoDB specifically?

MongoDB caps a single document at 16MB to keep documents fitting comfortably in memory and network buffers. An array that grows without bound — every comment ever posted, every log entry — eventually threatens that ceiling, and MongoDB doesn't gracefully truncate; it rejects the write outright once the limit is hit.
