Apache Pinot

I don’t think this is possible. I am getting `java.lang.IllegalStateException: Cannot read single-value from Collection` in the server logs.

you’ll need a transform function. let me pull up the doc

thank you <@UDRLN8MAP> you are always so responsive and helpful

<https://docs.pinot.apache.org/developers/advanced/ingestion-level-transformations#json-functions>

something like “foo_str”: “json_format(foo)” in your table config’s ingestion config

<@UDRLN8MAP> wow. it works. this is amazing. thank you.
