If I have a field which is boolean but the values are `'T'` and `'F'` , is there a way to use the typing helpers to cast them properly? using `th.BooleanType` makes it all true since the input strings are all truthy. Maybe a lambda?

Hi :wave::skin-tone-3:. Take a look at <https://sdk.meltano.com/en/latest/classes/singer_sdk.Stream.html#singer_sdk.Stream.post_process|https://sdk.meltano.com/en/latest/classes/singer_sdk.Stream.html#singer_sdk.Stream.post_process>

I kinda wonder if this is a nudge towards not updating raw data and just dumping it as is to the target, managing the post processing downstream… seems like it’d be clunky to apply that postprocess at the stream level (ie, keeping the type as string so that I can apply the T/F -&gt; true/false elsewhere)

oh, you can declare the field as `th.BooleanType` and use `post_process` to actually make it a boolean
