hi @tverdokhlebd, thanks your detailed spark log, from your description and dataset, key information
- run on local machine
- the size of each record is large
I noticed that OOM happened after parquet read old record to memory, which means we need to control the number of old records, so try add this option
```
.option("hoodie.write.buffer.limit.bytes", "131072") //128MB
```
