[jira] [Commented] (SOLR-9351) JSON Facet field should sometimes
default to facet.method=stream
[ https://issues.apache.org/jira/browse/SOLR-9351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15412078#comment-15412078 ]
Yonik Seeley commented on SOLR-9351:
------------------------------------
"stream" is fundamentally about not materializing the full result, but calculating it as the response is being streamed back.
It currently only supports sort="index asc", but we could support other sort orders and still stream I suppose.
bq. if limit is -1 or is a number that is at a decent proportion of the known available terms, then "stream" makes sense to me. And also, provided that the "base" docset (aka input domain) is large.
I think we need to compare the input domain vs the estimated number of terms in the field.

> The {{method}} on a field/term facet could be automatically set to "stream" in some cases and get better results?. For example if {{limit}} is -1 or is a number that is at a decent proportion of the known available terms, then "stream" makes sense to me. And also, provided that the "base" docset (aka input domain) is large.
