Thanks for submitting this PR!

Switching the data type from S to B makes sense, but would be a breaking change for existing customers that expect session data to be stored as a string.

Would you be interested in expanding this PR to adding a config option for data_attribute_type that would default to string, but allow binary to be used for the data_attribute? That configuration is handled in SessionConnectionConfigTrait.

Yes, sure, makes sense. I will add the config option, thank you for the advice :)

I went ahead and opened a PR to add this as an option: #1838

Thanks for raising this issue!
