Feat: Support Anomaly Detection for fields using valuesDoublesSketch. #411
Description
Summary
Lets add support for fields that use valuesDoublesSketch in Numalogic. Currently, we dont support this natively. This is a frequently asked/used feature and its better to have default Numalogic support out-of-the-box.
What change needs making?
I have created this branch and PR: (#409) which supports latency based anomaly for a particular use case but this needs to be generalized for wider adoption. Major changes include adding configuration/YAML support for postaggregations, aggregations, percentile on top of this PR. These fields should be config driven.
Use Cases
When would you use this?
We would use this when ever the input fields use Sketches(https://datasketches.apache.org/) to represent the value. This is used when we represent the "actual values" by "approximate values" trading accuracy for computation.
