Hi everyone. I'm new to metaflow and I think it is an amazing tool. My use case would be related to start using it as a data transformation tool from the beggining. So I have buit one simple workflow to transform data and generate a pandas dataframe by the end. The next step would be saving it somehow. So I have two simple questions: 1. Is there anyway we can store on metaflow directory some structured data, like .parquet files? It seems metaflow already deals with S3 in a decent fashion, but I'm not sure about what would be the best practices to serialize new files incrementally to disk; 2. I have seen from the discussions that there is currently no way to have composite workflows with dependencies. However, can I use one workflow to provide data to the other? Like, the ETL workflow would save some .parquet files that the training workflow will use. Thank you in advance. Really loving this tool.
