The following describes the current limitations of the Polaris Spark client:

-1. The Polaris Spark client only supports Iceberg and Delta tables. It does
not support other table formats like CSV, JSON, etc.
+1. The Polaris Spark client supports Iceberg, Delta, Hudi, and Paimon tables.
Other table formats like CSV, JSON, etc. are not supported for table operations
through Spark.
2. Generic tables (non-Iceberg tables) APIs do not currently support
credential vending.
### Delta Table Limitations
1. Create table as select (CTAS) is not supported for Delta tables. As a
result, the `saveAsTable` method of `Dataframe`
is also not supported, since it relies on the CTAS support.
2. Create a Delta table without explicit location is not supported.
3. Rename a Delta table is not supported.
-4. ALTER TABLE ... SET LOCATION is not supported for DELTA table.

+4. ALTER TABLE ... SET LOCATION is not supported for DELTA table.

+### Paimon Table Limitations

classpath.
