A. Thanks so much. This pr need to solved the issue with better approach.
Now I am more clear about overwrite semantic between table.overwrite and spark
sql overwrite for hudi.
B. Also spark sql for hudi overwrite should have the ability just like spark
sql 、hive 、 delta lake.
these engine have three mode for overwrite about partition:
1. Dynamic Partition : delete all partition data ,and the insert the new data
for different
2. Static partition: just overwrite the partition which is user specified
3. Mixed partition: mixed of 1 and 2
more detail in :
https://spark.apache.org/docs/3.0.0-preview/sql-ref-syntax-dml-insert-overwrite-table.html

C. our plan
1. Now spark sql for hudi overwrite is Dynamic Partition. I will resolved it in
this issue HUDI-1349, first support delete all partition in HUDI-1350, then
land HUDI-1349
2. Now spark sql for hudi does not support "Static partition" mode, will then
land it in
