Hi @mihaibudiu, I spent some time looking at Guava. Currently, it only provides `UnsignedInteger` and `UnsignedLong`. Other `UnsignedByte` and `UnsignedShort` are not provided by Guava. In addition, I found that MySQL provides another idea, we can handle them by mapping a wider range of Java types. For example, the `BIGINT` type is usually mapped to `java.lang.Long` for processing, while `BIGINT UNSIGNED` needs to be mapped to `java.math.BigInteger` for processing. For more type mappings, please refer to the document: https://dev.mysql.com/doc/connector-j/en/connector-j-reference-type-conversions.html Through this mapping conversion method, we do not need to add any classes, and the Calcite runtime can handle UNSIGNED types. What do you think of this approach? I will keep trying if you have any suggestions. -- This is an automated message from the Apache Git Service.
