Function transform_logical_batches_to_physical 

pub(super) fn transform_logical_batches_to_physical(
    table_batches: &[TableBatch],
    name_to_ids: &HashMap<String, u32>,
    partition_columns_set: &HashSet<&str>,
) -> Result<Vec<RecordBatch>>

Transforms logical table batches into physical format (sparse primary key encoding).

It identifies tag columns and essential columns (timestamp, value) for each logical batch and applies sparse primary key modification.
