Trino stored Iceberg column in lower case

[Zeev-Shavit]

Hi,
We ingest data into an Iceberg tables from Kafka topic.
The fields names in the topic coming in camel case, but the column names from those fields are written in lower case.
The ROW type column and ARRAY[ROW] column still consists nested fields as camel case.

When trying to query referencing the nested field, we got an error as follows:
Column '.'providerid'' cannot be resolved when the column providerid actually is ProviderId:
Select
<column_name>.ProviderId
from my_table

I tried using double-qouets:
Select
<column_name>."ProviderId"
from my_table

And single-quotes:
Select
<column_name>.'ProviderId'
from my_table
