3. For some of the tables, I can’t even figure out where the data would be coming from — for instance,
durationSort
isn’t a materialized view … but also doesn’t seem to have any writes I could find while spelunking the SigNoz codebase … how do these get populated? ditto
top_level_operations
, where from?

Hm, I saw
feature_manager.go
in my grepping, but it didn’t look like it was doing any writing — just creating the table; and I didn’t see any Clickhouse arguments that made it obvious how it’s receiving data. I see the
enableTimestampSortFeature
that adds a
PROJECTION
, but none for
durationSort
? I may just be dense! (this isn’t pressing, just curious)
