dagster: create asset for indexing EAS data

[ccerv1]

Describe the feature you'd like to request

We'll probably just want to start by dumping raw attestation data into a data lake

Describe the solution you'd like

A crawler similar to the open_collective.py example that fetches attestations from the EAS graphql endpoint and dumps that standard data plus a JSON with the decoded schema data into BigQuery.

Here's an example: https://gist.github.com/ccerv1/12a83e4a698a200a48ac17b97b049241

Describe alternatives you've considered

Ask the EAS team if we can get a mirror of their database

Recoping this issue:
I think we prefer to do it this way
#2069

So once we have a generic trace decoder, we can use that to decode EAS traces.

@Jabolol could you take a look at the PR above? TY!

@ccerv1 Done! I made several adjustments to the PR, but the core contribution was definitely useful. I’ve tested it both locally and on BigQuery, and everything is working well.

On the flip side, I found yet another concurrency bug with Dagster. Apparently, each define_asset_job call can only have one partitioned run, so Open Collective and the new EAS assets clash. I'll create an issue to track and fix it.

Let me know if you need anything else!
