I'm in the process of evaluating DSE for our project and before I take the time to try to construct a scenario, I figured I'd see if anyone already knows the answer.
Assume you have a large column family with millions of records (some of them quite large) that is indexed into SOLR. Now, assume you upload a new schema that indexes a few new columns that weren't previously indexed.
My understanding is that DSE will automatically go through and reindex all of the data into solr. However, my question is whether or not the original index is still accessible during this time or if it is immediately invalidated. That is, if it takes 2 hours to reindex all the data, can I still search against my old index and all of the columns that it indexed and find data that has yet to be reindexed with the new schema?
Thanks!
Jason
