[Bug]: Managed IO for Iceberg cannot query by partition

[saathwik-tk]

What happened?

Lets say, I have field1 (string type) as my partition field, and there are many other fields, field2, field3, field4....
Querying the data with " select * from iceberg_table where field1 = 'field1_example_value'; " returns no data
but when querying with " select * from iceberg_table where field2 = 'field2_example_value'; " returns the data as expected.
I have ingested the data through Managed IO of Iceberg,
pipeline.apply(Managed.write(Managed.ICEBERG).withConfig(config_map);
Please have a look into this issue.

@ahmedabu98 any ideas here?

Hey @saathwik-tk, can you provide a little more context?

• which catalog are you using?
• what does your write configuration look like?
• did you create the Iceberg table beforehand?

Also a reproducible example would be helpful to find an RCA
