Leonard Xu commented on FLINK-17657:
[~zhanglun] Thanks for the report, it's a bug from type mapping between mysql
and flink sql type exists in JDBC connector.
the root cause is that bigint unsigned range is {{0}} to
{{18446744073709551615, }}{{bigint rang is }}{{-9223372036854775808}}{{ to
}}{{9223372036854775807}}{{. so we cannot map a bigint unsigned to bigint(flink
bigint has same range with mysql bigint)}}.
[~JinxinTang] 's work around[1] is read String rather read the original
BigInteger(jdbc treats bigint unsigned as java.math.BigInteger).
