Hello
Is it possible for a single Prometheus to have multiple remote_write adapters depending on jobs ?
For example job1 should be writing to r1 (cortex) and r2 to another remote_write instance ?
Another problem I face is certain jobs only need to do remote_write and certain jobs locally. Please let me know if that’s possible at job level

Although I'm not using it: As far as I understand, multiple remote write
configs are supported.
Each remote write config can have write_relabel_configs which allow you
to filter what to send. This works per-remote write target.

Yes, this should be possible using the same mechanism by filtering on
the job label.
Kind regards,
Christian

Remote writes can be filtered using write_relabel_configs. See:
and in particular the "drop" action. You can filter by any labels, including job.
You can't disable local writing. Prometheus uses it for alert rules and recording rules.
