How to resolve `ValueError: Error apply transform “left join”` when joining 3 BigQuery tables in Dataflow using Job builder?
I have 3 tables from a BigQuery dataset as data sources: tableA, tableB, tableC. I am trying to join tableA and tableB on column idAB and tableB and tableC on column idBC. I am using a Join transform, with all the tables as the input steps, and the join equalities as specified:
GCP datflow job connecting to a GCP VM instance running an HTTP Server
i have a GCP Dataflow application and i am planning invoking REST commands to a FAST API server running on one of my VM hosts
I am planning for my VM not to expose an external IP address (as i dont want to be hit from the outside)
How can my GCP dataflow connect to my VM?do they need to reside in the same network?
Could anyone pls advise?
Kind regards

Make a SSL cert file available in worker node in Dataflow using Python SDK
I need to connect to a Kafka cluster using SSL certificates.
I have tried deploying the job by keeping the SSL files in GCS bucket, but that doesn’t work.
I also tried to copy the file from GCP to a "/tmp/" location, assuming that file will be downloaded in the worker node, but to my surprise, it got downloaded in the local server from where I am submitting the job.
