@Viridian: Your interim solution sounds good. That's what we've been doing in posts that we make that use self-serve.
Regarding the ability to delete datasets. We hear you. The feature isn't available on the platform right now, but if you're close to your limit and you want to add new datasets, you can email in to [email protected] and we can delete them manually on our side to make some room.
For the update/replace request, have you tried issuing updates in a live updating dataset? You should be able to provide updates in a nightly update file by adding a record with the date and asset of the historical record you'd like to update. Note that this will create an 'update' record on our end with a timestamp according to when the update was issued and pipeline will only learn about the update based on the timestamp (i.e. you won't see the update processed until day N of a simulation if you posted the update at 1am ET on day N).
The above behavior is one of the most critical pieces of self-serve. Having a point-in-time history of updates to self-serve datasets means that algorithms using self-serve data can be evaluated for an allocation. If it were possible for for data to be overwritten, we wouldn't be able to tell whether or not the dataset has lookahead bias. By adding a timestamp to the live updates, the dataset can build up an out-of-sample period, which is critical to our evaluation process.
That said, I recognize you might just want to update a historical dataset where you discovered a data bug or other issue. Right now, the best way to make that update is to email in to us to get the old version deleted and then upload the new version with the fix. This further stresses the need for your first request of adding the ability to delete a dataset, but again, emailing in is the best solution right now. I've passed along the feedback to the team that works on self-serve to let them know about your requests. Thanks for the feedback.
P.S. I think it's great that you want to share your dataset with the rest of the community!
