Only you can answer this question. We know nothing about your dataset. If each data record in your source system does not change once it has been created, then you should only need to do a full reindex when you change something about Solr's index configuration that requires a reindex. Most changes to the schema do require a reindex. Other config changes might require a reindex. If the data for an existing record in your source system can change, then to avoid a full reindex, you would need some way for the delta updates to notice that an existing record has been updated so it can be indexed again. A proper uniqueKey field in the schema is required for this to work without a full reindex. Thanks, Shawn
