@xuchang-66 @TechTinkerer42 I have tried to test this with `write.distribution-mode = none` and it can indeed help to improve the performance but can introduce the problem of small files. But we can control number of file created by repartitioning the input data on some column which can also distribute the data in each of the spark partition evenly and number of repartition should be a factor of number of cores. Each spark partition will create one file if we are writing to a single partition. -- This is an automated message from the Apache Git Service.
