This is not the essence of the problem, what the question actually wants to ask is the problem of inserting data with Impala JDBC, Chinese strings being truncated and garbled.

Thank you very much for your answer, which made me realize that my understanding of kudu partition tables is very inadequate, especially in terms of usage restrictions. Once again, I would like to express my gratitude to you and wish you a happy life.

The current cluster has 7 tablet servers and 448 CPU cores. It is planned to set Hash partitions to cooperate with Range partitions. The Range partition divides the ten year data into 120 partitions by month. How many Hash partitions based on other fields is appropriate? In addition, the main read/write scenario is a large number of reads/writes based on the current month's data.
