------------------------------
Summary: Provide an option for serializing DECIMALs in JSON as
plain number instead of scientific notation
Key: FLINK-20861
URL: https://issues.apache.org/jira/browse/FLINK-20861
Project: Flink
Issue Type: Improvement
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Reporter: Q Kang
When using DECIMAL types in Flink SQL along with JSON format, it is quite
common to see that some large values are written out as scientific notation.
For example:
Definition: `orderId DECIMAL(20, 0)`
Input: `\{"orderId":454621864049246170}`
Output (without transformations): `\{"orderId":4.5462186404924617E+17}`
However, values in plain numbers are easier to understand and more convenient
for the case shown above. So we can provide a boolean option (say
`json.use-plain-decimals`?) to make this behavior tunable.
