- Some values of some supported data types may not be casted, below are known issues:
1）When casting VARCHAR/NCHAR to BIGINT/BIGINT UNSIGNED, some characters may be treated as illegal, for example "a" may be converted to 0.
- 2）There may be overflow when casting singed integer or TIMESTAMP to unsigned BIGINT
- 3）There may be overflow when casting unsigned BIGINT to BIGINT
- 4）There may be overflow when casting FLOAT/DOUBLE to BIGINT or UNSIGNED BIGINT
+ 2）When casting to numeric type, if converted result is out of range the destination data type can hold, overflow may occur and casting behavior is undefined.
+ 3) When casting to VARCHAR/NCHAR type, if converted string length exceeds the length specified in `type_name`, the result will be truncated. (e.g. CAST("abcd" as BINARY(2)) will return string "ab").

maxFirstStreamCompDelay 是 stream 第一次执行前最少要等待的时间。
streamCompDelayRatio 是延迟时间的计算系数，它乘以查询的 interval 后为延迟时间基准。
maxStreamCompDelay 是延迟时间基准的上限。
实际延迟时间为一个不超过延迟时间基准的随机值。
stream 某次计算失败后需要重试，retryStreamCompDelay 是重试的等待时间基准。
实际重试等待时间为不超过等待时间基准的随机值。
