Previously
parallel-transform-web
was running up to N transform tasks concurrently, but while those tasks were running it buffered the rest of the stream data internally 🤦 .This was resolved in alanshaw/parallel-transform-web#1 so just pulling in the latest code here.
I was seeing memory usage in w3cli for a 12GB file grow to ~10GB but now it stays at around at round ~4GB (which is the same usage I see when I remove
parallel-transform-web
and replace it with a regular serialTransformStream
).
