TSIA. I have a Solr Collection of questions asked by users (our own internal AUA). Every time a user submits a question, the question is inserted into a database and the Solr Collection reindexed.
Just on the small chance that two users submit a question at about the same time, I don't want the second question to trigger a reindex until after the first question reindex is completed. So is it possible to lock a Solr Collection each time it is automatically reindexed?
