Here's the result for the script that reads the whole file and counts the total number of rows. | order | repartition | wall time (s) | memory (mb) | read sorted order | | -- | -- | -- | -- | -- | | true | true | 1.24 | 654 | ✅ | | true | false | 1.65 | 944 | ✅ | | false | false | 0.55 | 45 | ✅ | | false | true | 0.41 | 151 | ❌ | It seems like order=false and repartition=false seems to be the holy grail of performant, low-memory footprint streaming in sorted order.
