sadly it seems that there are at several issues:
- gdpr has less detailed data so it's hard to generate a proper ID at times
- sometimes there is a small (1s?) discrepancy between created_at between same event in GDPR an API
- some API events can have duplicate payload, but different id, which violates uniqueness
Instead my.github.all should be used (still backward compatible)
The reasons are
a) I don't feel that grouping (i.e. my.coding.*) makes much sense
b) using .all pattern (same way as twitter) allows for more composable and cleaner separation of GDPR and API data
