I am looking for a spark connector for writing the data to pinot. I saw on github, that write support will be availible in the future. Do you have any news about it or tips how to deal it? Thank you in advance !

we currently don't support writing spark dataframes/RDDs directly to Pinot. However, you can use our spark plugin to read your data and dump into pinot's storage. You can find the documentation here - https://docs.pinot.apache.org/basics/data-import/batch-ingestion/spark
