WTa-hash opened a new issue #4593: URL: https://github.com/apache/hudi/issues/4593
Does Hudi support column re-ordering if there are no column additions/removals? According to https://hudi.apache.org/docs/schema_evolution/, it states that "Add a new nullable column and change the ordering of fields" is not supported. So if I perform only the 2nd half of that statement, which is "change the ordering of fields", will Hudi support this? **To Reproduce** Steps to reproduce the behavior: In my test script, I have 3 sets of data, 1) initial data, 2) update #1, 3) update #2. In update #1, I'll be re-ordering the columns. 1. Run test script: [TestData.txt](https://github.com/apache/hudi/files/7865586/TestData.txt) 2. Observe output. Initial Data  Update #1  Update #2  **Expected behavior** Does Hudi officially support just column-reordering? My existing Hudi table may have a certain column order, while the incoming data batch will contain the same columns but in different order.
