@HuangZhenQiu to be honest I still have a doubt on the whole parquet support for DECIMAL. parquet [doc](https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#decimal) says that the primitive type (int32, or int64) stores the unscaled value (before the decimal point) but I sill don't know where is the scaled value (after the decimal point) stored in the parquet field. As the support for int64 in flink was already done through _BasicTypeInfo.INT_TYPE_INFO_ I did the same but I fear we lose the decimal part in those cases. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
