   Before we wrote about `3600 fields` in the hudi table, but the writing 
performance did not improve. Today we did another test, reducing the number of 
fields in the hudi table. The number of fields in the hudi table was adjusted 
to `1000`. The writing performance has been greatly improved, and the 
consumption speed of Kafka has been greatly improved, which can keep up with 
the production speed. 
   
   But we can't determine which step in hudi takes a long time to cause?
