@andygrove I have noted down the benchmark result here : https://github.com/apache/datafusion-comet/pull/3904 this the table I got : | Metric | main (baseline) | After single spill file | Delta | |--------|----------------|---------|-------| | **avg write time** | 1.376s | 1.113s | **-19.1%** | | **min write time** | 1.349s | 1.106s | **-18.0%** | | **max write time** | 1.415s | 1.126s | **-20.4%** | | **throughput** | 3,633,169 rows/s | 4,490,434 rows/s | **+23.6%** | | write time (I/O) | 0.113s (8.2%) | 0.037s (3.3%) | **-67.3%** | | encode time | 0.745s (54.1%) | 0.726s (65.2%) | -2.5% (noise) | | repart time | 0.041s (3.0%) | 0.041s (3.7%) | 0% | | output size | 226.20 MiB | 4.38 MiB | writes compressed data during the spill phase, so the final output file contains already-compressed data | | spill count | 10 | 10 | identical | | data size (in-memory) | 440.36 MiB | 440.36 MiB | identical | -- This is an automated message from the Apache Git Service.
