Henrik commented on SOLR-8621:
------------------------------
Hi [~cpoerschke] and others,
I couldn't find an upgrade document for {{mergeFactor}}, so I'll just ask here.
This is my current config:
{code}<indexConfig>
<mergeFactor>6</mergeFactor>
<maxIndexingThreads>8</maxIndexingThreads>
</indexConfig>{code}
If want the exact same behaviour as I currently have, how should it look in
Solr6? I can't find mention of {{maxIndexingThreads}} in
https://cwiki.apache.org/confluence/display/solr/IndexConfig+in+SolrConfig and
I haven't figured out if the "old" policy is {{TieredMergePolicyFactory}} or
{{LogMergePolicy}}.
Thanks.
> solrconfig.xml: deprecate/replace <mergePolicy> with <mergePolicyFactory>
