Do you remember the first example with the Wikipedia data? We asked our fellow DB expert to import the data dump into PostgreSQL and we fetched the data from there. But what if our colleague is sick and can't help us, and we need to import that data? We can parse the data and send it to Solr, but that's not an option – we don't have much time to do that. So what to do? Yes, you guessed – we can use Data Import Handler and one of its data sources, file data source. This task will show you how to do that.
Please refer to the How to properly configure Data Import Handler recipe in this chapter to get to know the basics of the Data Import Handler configuration. I assume that Solr is set up according to the description given in the mentioned recipe.
