Why does data transformation traffic cost several times higher than read and write traffic?

Data transformation traffic is calculated based on the volume of uncompressed data that is transformed. Read and write traffic is calculated based on the volume of data that is transmitted after compression. The volume of transformed data depends on the complexity of the log content and the number of indexed fields. For example, if you have 10 GB of source data that generates 8 GB of index data and is compressed to 2 GB for transmission, the data transformation traffic is 8 GB and the read and write traffic is 2 GB.
