@gianm Thank you for taking at look. Designing this as an `InputSource` is
something I'd considered but my concern is that wouldn't it create a dependency
across extensions? If the IcebergInputSource implicitly identifies that it
needs to delegate to HdfsInputSource, wouldn't the hdfs extension need to be
available to the iceberg extension in compile-time?
Or are you suggesting that `IcebergInputSource` would be similar to a
`CombiningInputSource` design where the delegate input source is also specified
in the spec like:
"ioConfig": {
"type": "index_parallel",
"inputSource": {
"type": "iceberg",
"tableName": "logs",
"namespace": "webapp",
"partitionColumn": "event_time",
"intervals": ["2023-01-26T00:00:00.000Z/2023-02-18T00:00:00.000Z"],
"delegateInputSource" : "hdfs"
}
}
