Apache Druid

It looks like the answer to your question is yes.

I'm looking at the <https://druid.apache.org/docs/latest/development/extensions-core/kafka-supervisor-reference.html#specifying-data-format|Specifying data format> doc:

&gt; Kafka indexing service supports both `inputFormat` and `parser` to specify the data format. Use the `inputFormat` to specify the data format for Kafka indexing service unless you need a format only supported by the legacy `parser`.


The <https://druid.apache.org/docs/latest/ingestion/data-formats.html#input-format|input format doc> continues:

&gt; You can use the `inputFormat` field to specify the data format for your input data.

And includes <https://druid.apache.org/docs/latest/ingestion/data-formats.html#parquet|Parquet> as a supported data format. Just make sure to load the <https://druid.apache.org/docs/latest/development/extensions-core/parquet.html|Druid Parquet extension>.

At the moment right now, at least based on my past experience, you cannot consume parquet file from a Kafka topic.

even with `inputFormat`? I would think it does work using `inputFormat`, although I never tried it!

yes, I set the inputFormat to parquet and it didn’t work. Unless something changed recently. We tested it 3 versions ago.
