Hi Eduardo, And As we are trying to build an advanced search functionality in which we can able to do partial search based on actor, producer, director, etc. columns. So if we do denormalization of tables then we have to create tables such as below :- video_by_actor video_by_producer video_by_director video_by_date etc.. By using denormalized, Cassandra only allows us to do equality search, but for implementing Partial search we need to implement solr on all above tables.
This is my thinking, but I think this will be not correct way to implement Apache Solr on all tables.
