I am getting downvoted here without anybody actually addressing my arguments - TFX/Beam being replaced by TFX/KubeflowPipelines and the new platform being plugged in tightly to Google's managed services (AI platform, BigQuery, GCS, etc). I didn't think my tone was negative - they are observations that nobody in this subthread is addressing.
As a systems person, TFX to me was a layer on top of Beam to tie ML pipelines together. Now, Beam is gone - dataflow appears as a managed service you can use in your pipelines (see the figure on the blog post). TFX is being repackaged as the API for Kubeflow pipelines. That was my take and what i wanted to discuss.
