Answer
Use streams, chunk processing, backpressure handling, zero-copy transfers, and minimal memory buffering for GB/TB-scale ingestion.
Quick Answer
Massive file ingestion optimization: stream files directly without buffering (fs.createReadStream + pipeline), process in chunks, use worker threads for CPU-intensive parsing, limit concurrency to avoid overwhelming I/O and memory, use back-pressure to control ingestion rate, and write to the database in batches rather than per-record inserts.
