ofirnn opened a new issue #11275:
URL: https://github.com/apache/druid/issues/11275
After upgrading to 0.21.0 we noticed that the legacy UI (old-console)
endpoints are not working anymore. our cluster is pretty big (thousands of data
sources, a-lot of segments) - making the unified console in the router mode to
not work.
### Affected Version
0.21.0 (and all versions when legacy UI isn't working anymore)
The Druid version where the problem was encountered.
### Description
When having:
- ~3500 data-sources
- ~20,000 segments
Router mode:
- Datasources page isn't working in router mode - the SQL query endpoint
hangs
- Segments page isn't working in router mode - SQL hangs
Coordinator mode:
- Datasources page working well in coordinator mode- but without the
segment timeline view
- Segments page crashing in coordinator mode - making thousands of requests
- one per datasource - crashing chrome with insufficient resources
More:
- no way to filter prior query in both segments and datasources page
- no way to save a preset of filters with the responsive UI
- Ingestion page seems to work well even under high pressure of tasks
(20-30k daily tasks)
All of the above worked well in the old-console - which we didn't find a way
to enable in 0.21.0 - we saw a commit completely remove the binding so I
believe there's no way to use it anymore.
