Describe the Bug

• Detection of sources in analytics_sources.pipe is done using the current domain from the first event that arrives. This works fine on setups where there is only a single source, but when there are many it can lead to false positives: the current domain may change from event to event.

Expected Behavior

When multiple events arrive together they should be processed using the current domain from each one.

To Reproduce

Send multiple events with different href and referrer. The current domain from the first event is used for all of them.

Details

This behavior is particularly problematic with the Tinybird gatherer, as it coalesces multiple events and sends them together. It also leads to memory issues in certain setups with billions of events.
