This is independent of DIH. If you want to add a new field to the schema, you should reindex. 1M documents should not take that long. > - need to populate data from a file that has a key and value per line and i > need to use the key to find the doc to update and then add the value to the > new schema field It is best just to reindex, but it should be possible to write a script to pull the doc from the existing Solr index, massage the return format into Solr's XML format, adding a value for the new field in the process, and then posting the new file to Solr for indexing.
