this I think is in line with what we do in other java connectors 👍

You can add a test also for binary type

Does that mean that a binary field in the source database is encoded as a AirbyteType String? Is that something that was discussed, or just how it was implemented for simplicity reasons?

the current behavior for binary column is undefined in our public doc (and see slack discussion with destination team here https://airbytehq-team.slack.com/archives/C03C4AVJWG4/p1700173565688209), it sounds like base64 is the direction we are heading to; so yes mostly for simplicity reason.

node.put(columnName, value);
