>
> Records can be overwritten when the recordkey or primarykey is binary type,
> such as a mysql table with primary key BINARY(16). There may be only one
> record in hudi finally after writing. This is related to the toString of
> ByteBuffer when generating the record key. ByteBuffer has overwritten the
> toString to return a summary string.
