> What are our plans for Shredded variants? There are cases when some part of the Variant is stored in its own column. See: #13219 In this PR, for the read path, the shredding-related work is implemented in the Iceberg Parquet layer. This logic is aligned with the Spark side, so it should be supported. For the write path, we haven’t implemented shredding yet. On the Flink side, Variant type support is currently limited to `BinaryVariant`, so what Flink writes is only unshredded data. If we want to support shredding, we may need to add a new config option, such as `shreddingSchema`, to predefine which fields should be shredded, and possibly introduce something like “auto” as well. We’ll need to align this with Spark’s logic later. This is just my own preliminary understanding. -- This is an automated message from the Apache Git Service.
