Is there a quick way to determine via context if an asset has ever been materialized?

Hey @Charlie Bini - I created a discussion to answer this, because I suspect others might be curious too: https://github.com/dagster-io/dagster/discussions/12666

very nice!

Charlie isn't an asset that had a run failure a different state than one that has never materialized? The behavior you describe is what I would expect. It did materialize, just not successfully. There could be many reasons for this, but I would expect to look at the status of the materialization for more info, not to have it show up as never materialized.

Hi all, I am wondering if there has been any success using the provided GitHub code? I have asset A being updated daily. Then, end of week I want to save a snapshot of asset A as asset B for use with an op that compares the changes of asset B weekly. It looks like my issue is only on the instantiation of the pipeline similar to the above: the provided code fails, then returns a materialization record upon retry but fails because asset B does not yet exist. So my full question is, is it possible to do something along the lines of the below?

if context.instance.get_latest_materialization_event(asset_A_key) is None:
           return empty_dataframe
else:
           return asset_b_dataframe
