detection dimensional cache
jihaozh opened a new pull request #4336: [TE] detection dimensional cache
URL: https://github.com/apache/incubator-pinot/pull/4336
For high dimensional metrics, currently, the detection will send a query for each dimension and then run the anomaly detection. This PR implements an optimization to fetch time series for multiple dimension values at once from Pinot and run detection. This could reduce the number of queries sent to pinot and improves the overall detection performance.
- Support batch loading in time series loader
- Support send the request for multiple dimension filter sets in one Pinot query
- Move the caching from Anomaly Detector Wrapper to Dimension Wrapper
