This installment of the tutorial covers how to efficiently import large CSV files into RediSearch, a full-text search engine, using Node.js and the Async queue library. The tutorial uses the TMDB dataset to demonstrate how to ingest data from two different files: movies and cast/crew. The process involves parsing the CSV file, creating an index in RediSearch, and then searching for specific documents using a script that takes a search string as input. The tutorial also covers how to get individual documents from RediSearch using a similar script, and provides scripts to drop existing indexes and run search queries. By the end of this installment, users should have a good understanding of how to manage the lifecycle of a dataset in RediSearch.
