[jira] [Commented] (SOLR-9026) Design Facet Telemetry for non-JSON field facet

["Yonik Seeley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-9026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15264221#comment-15264221 ] 

Yonik Seeley commented on SOLR-9026:
------------------------------------

Looking good... a couple of quick points:
- "facet-trace" is the same name used for JSON Facet API, right?  If both faceting components are used at the same time, does this work?
- it seems like one would really want elapsed time per facet.field (i.e per-sub-facet)?
- instead of changing "long elapse" to "Long elapse", perhaps just use "-1" to detect if it's been set?
- "fdebugCurrentTermCount" is oddly named... perhaps just "fdebug"?

> Non-JSON facet is widely used and telemetry is helpful is diagnosing expensive queries. As first step, the JIRA is to design telemetry for field facet.
> Example: (using films)
> {code}
> $curl 'http://localhost:8228/solr/films/select?debugQuery=true&facet.field=genre&facet.field=directed_by&facet=true&indent=on&q=*:*&wt=json'
> ...
>     "facet-trace":{
>       "elapse":1,
>       "sub-facet":[{
>           "processor":"SimpleFacets",
>           "elapse":1,
>           "action":"field facet",
>           "maxThreads":0,
>           "sub-facet":[{
>               "method":"FC",
>               "inputDocSetSize":1100,
>               "field":"genre",
>               "numBuckets":213},
>             {
>               "method":"FC",
>               "inputDocSetSize":1100,
>               "field":"directed_by",
>               "numBuckets":1053}]}]},
> ...
> {code}
