GDPR Data Subject Tool: Allow finding a user only through visits segment #12976
Labels
c: Performance
For when we could improve the performance / speed of Matomo.
Milestone
We should only allow and only show segments that are based on the
log_visit
table.All other segments should usually not be needed anyway to identify a data subject. And if so, it could be later still done potentially through the visitor log and segmentation. Although I doubt it is needed.
Why? Because this DB query will query over all visits, joining a segment with
log_link_visit_action
(or other tables) can not only take a really long time to find the data subjects, it could even result in the worst case maybe in temporary tables etc.I think it would also make the tool slightly easier to use by showing only more relevant segments.
@mattab any chance to have this in 3.6.0?
