   @NarayanB The two parameters you want to look at are `basename_template`, which defines the filename, and `existing_data_behavior`, which controls how PyArrow responds to existing files. `existing_data_behavior` should be `"error"` by default, which should prevent overwrites. See: https://arrow.apache.org/docs/python/generated/pyarrow.dataset.write_dataset.html#pyarrow.dataset.write_dataset
   
   I'm not sure what you mean by "slice the table". How did that produce overwrites? Do you have code you can share?
