@parisni we want sparksql tread hudi as DataSource table to have a better
performace.
when spark read dataSource table, spark will restore table metadata from
table properties(include table schema )
you can see the original code in spark
HiveExternalCatalog.restoreTableMetadata
* It reads table schema, provider, partition column names and bucket
specification from table
* properties, and filter out these special entries from table properties.
