What is it that triggers DSE 2 to re-index? That is, I have created a core using the HTTP APIs and POSTed solrconfig.xml, schema.xml etc. I then POSTed Solr XML formatted content to the Solr port (8983) of DSE 2. I can see the keyspace and column family exist, and I can see the config files, as well as rows in the CF keyed by the document IDs. If I describe the keyspace, I can see all of the fields defined as columns, configured with a CUSTOM secondary index etc.
I'm currently making changes to both solrconfig.xml and schema.xml in order to work with the Solr FactVectorHighlighter to hopefully improve highlighting performance. In the past, if I changed schema.xml, I'd have to feed all of the content to Solr again. How does this work with DSE? When I post either file there is quite a bit stuff logged regarding applying a migration an updating the column family, as well as outputting the fields defined in schema.xml.
The DSE docs describes how data can be inserted via Cassandra or Solr. But, with data already in place, when I modify schema.xml, how do I re-index that existing data? Is it automatic or do I have to trigger it in some way?
