Subject Re: [ANNOUNCE] Apache Solr 8.6.0 released
Date Fri, 17 Jul 2020 00:49:34 GMT
Thanks Aroop for your feedback. We shall try to ensure continuity of
functionality via packages. Your help in those efforts would be greatly
appreciated as well. Let us take this discussion to SOLR-14660.

> Is there a replacement for DIH?
DIH is available as a community supported package. However, it is an
anti-pattern for a search engine to be pulling data from outside. Instead,
please consider writing separate indexing programs that pull data from the
database systems and index into Solr. It is not only a good practice, but
also more efficient in terms of throughput. For more information on this,
please start another thread in solr-users@ list, and more people can
suggest best alternatives here.
