/**
* In some scenarios uint16_t (0~65535) is used to store the row len.
* - Firstly, we use 65531(65535 - 4), as the SDataRow/SKVRow contains 4 bits header.
* - Secondly, if all cols are VarDataT type except primary key, we need 4 bits to store the offset, thus
* the final value is 65531-(4096-1)*4 = 49151.
*
* History value:49151/65531
* - 65531 compatible with 2.0
