Similarity: BTW also I had the same questions for similarity search inside / across datasets. I hope Meltano can help in providing some more visibility to such kind of processes that usually just happen in some Python / SQL script "somewhere o the server". It would be so nice to have these issues picked up by Meltano devs with a nice Blog post or at least some hints - of maximum joy of course would be an example project for deduplication and similarity search. I believe that would also trigger a lot of interest, because these are so essential operations in many data processing (cleanup) pipelines, so it would be of good marketing value as many people will read that!
