 The Variant type is designed to store and process semi-structured data efficiently, even with heterogeneous values.
 Query engines encode each Variant value in a self-describing format, and store it as a group containing `value` and `metadata` binary fields in Parquet.
-Since data is often partially homogenous, it can be beneficial to extract certain fields into separate Parquet columns to further improve performance.

 This process is **shredding**.
 
 Shredding enables the use of Parquet's columnar representation for more compact data encoding, column statistics for data skipping, and partial projections.
