Is it not possible to create a partioned iceberg table with AWS Glue createTable?

Question

I'm calling glue to create an iceberg table, but neither `PartitionIndexes` or `TableInput.PartitionKeys` is accepted by Iceberg tables.

```js
await glue.createTable({
  DatabaseName: 'test',
  OpenTableFormatInput: {
    IcebergInput: {
      MetadataOperation: 'CREATE',
    },
  },
  TableInput: {
    Name: 'test',
    StorageDescriptor: {
      Columns: [
        { Name: 'column_a', Type: 'date' },
        { Name: 'column_b', Type: 'string' },
      ],
      Location: 's3://test/test',
    },
  },
}).promise();
```

Is there something equivalent to using `PARTITION BY` in athena?

Answer

You shouldn't create Iceberg tables manually, configure the Iceberg library to use the Glue catalog and register a reference when writing the data.  
https://iceberg.apache.org/docs/latest/aws/#spark  
Iceberg doesn't use standard table partitions, the partitions in Iceberg are handled internally by the metadata (so they are dynamic).
