Unique identifier for binlog rows (question?)

[cubbuk]

Is there a way to get a unique identifier from binlogs for each log, something like uuid for example?
I am sending logs to a kinesis stream and there is a consumer which reads the data to save into db. If there is a unique identifier for each log, then reprocessing the records wouldn't create duplicate data on the final destination. I thought about using nextPosition and timestamp but realized non of them are unique actually. Any idea how to get such an information?
Thanks
