- It's not possible to see per-stream input metrics in the app, only aggregate metrics.
- Pagination query parameters are ignored in List APIs (eg: GET /pipelines, /streams, /connections).
- Custom stream retention settings are not yet user-facing. For now, contact support if you need help adjusting stream retention.
- The REST and Datagen connectors do not currently expose metrics.

askeyword to provide a name (e.g.
select 2 + 2 as hopefully_four ...,
select to_timestamp(ts) as ts ...).
- When performing windowed aggregation, you must
group byboth the generated
- Sliding windows (i.e. the
hop()function) require the size argument to be a multiple of the slide interval. As an example,
hop(table x, descriptor(ts), interval '1' second, interval '60' seconds)is valid while
hop(table x, descriptor(ts), interval '3' seconds, interval '5' seconds)is not).
- Session windows are not currently available.
