Documentation on Streaming Quantiles and Digests in 2.4 #1025

Closed bearrito closed 6 years ago

bearrito commented 7 years ago

I'm very interested in the use of Streaming Quantiles!

Is there any documentation on the usage? Maybe I just missed it?

bearrito commented 7 years ago

I now see this - http://opentsdb.net/docs/build/html/api_http/histogram.html?highlight=histogram

To clarify I'm more interested in how to gain access to the features mentioned in https://www.slideshare.net/HBaseCon/opentsdb-hbasecon2017. In particular, the usage of datasketch library. I currently use this from Storm and would love to use it in a more native fashion.

Edit: We use the Java API directly if this matters.

I'll finish up the docs, make sure they're good but the plugin mentioned in HBaseCon can be found at https://github.com/OpenTSDB/opentsdb-datasketches. I don't have a release yet so you just have to run the mvn package and copy it to your plugin directory. The readme has some details on how to create the sketches/histos. Then if you're using the JAVA API, you would call TSDB.addHistogramPoint() to write the values. Hope that helps :)

I think I have a deeper question, which I'll ask on the usergroup.

Thanks for the response!
