- Empty source plan that generate record batch with two columns:
HistogramFoldwill fold the conventional (non-native) histogram (1) for later computing.- Manipulate the input record batch to make it suitable for Instant Operator.
- Time series manipulator for range function.
ScalarCalculateis the custom logical plan to calculatescalarin PromQL, return NaN when have multiple time series.- Assume the input stream is ordered on the tag columns.
- Normalize the input record batch. Notice that for simplicity, this method assumes the input batch only contains sample points from one time series.
- A special kind of
UNION(ORin PromQL) operator, for PromQL specific use case.
