Description
The
can_cast_typesis a bit to flexible with decimals, since we define the decimal type in the table metadata. So if the source data contains a decimal that is larger than the decimal in the table metadata, we should throw an error. Before we would let our writer just write becausecan_cast_typesdoes not check precision and scale for casting so Decimal(30.1) could be written after the table was set to only allow precision=1, scale=1.After the write, the json parser would not be able to read the table anymore since it throws a decimal overflow, and rightfully so. This fix will prevent tables to get in these invalid states.
