Single document update is quite possible! No worries there.
Since you’re using DIH (data import handler) you can use the delta-import
command, see
https://cwiki.apache.org/confluence/display/solr/Uploading+Structured+Data+Store+Data+with+the+Data+Import+Handler#UploadingStructuredDataStoreDatawiththeDataImportHandler-DataImportHandlerCommands
You’ll need some way to determine what a “new” document is. DIH provides the
last indexed timestamp that you can leverage in the delta query configuration
to pick up documents since that time.
