[~shaie] wrote in SOLR-5730:
bq. ... How about if we introduce a MergePolicyPlugin/Factory, which would
allow one to implement whatever MergePolicy he wants (including wrapping
others). ...
[~cpoerschke] wrote in SOLR-5730:
bq. I like the idea of a {{MergePolicyFactory}} ... We currently have
{{mergeFactor}} and {{maxMergeDocs}} elements alongside the {{mergePolicy}}
element. I would see the {{MergePolicyFactory}} route as an opportunity to
deprecate the mergeFactor/maxMergeDocs/mergePolicy elements i.e. for a
transition period users can use the existing/deprecated elements or the new
mergePolicyFactory element but eventually we will remove the deprecated
elements. ...
