@Marostegui today we ran Similarusers ingestion of April data. Some stats:

Loading /home/gmodena/similar-users-private/data/2021-04/temporal.tsv: 18742350rows [57:18, 5450.29rows/s]
Loading /home/gmodena/similar-users-private/data/2021-04/metadata.tsv: 8370839rows [29:25, 4742.03rows/s]

Model=Temporal  Read=18742350   Skipped=0       Inserted=18742350
Model=UserMetadata      Read=8370839    Skipped=0       Inserted=8370839
Model=Coedit    Read=112013275  Skipped=0       Inserted=112013275

I kept the process monitored, but from what I could tell, all seemed fined on the database I/O front.

Excellent! Thanks for the ping :)

Hey @Marostegui; is it ok with you if we ingest May data without giving an heads up upfront (like we did for April)?
