Fast JSON Indexing in SQLite Using Virtual Columns

This article discusses the topic of JSON virtual columns in SQLite and how they can be indexed to improve query performance. JSON virtual columns allow the storage of data in JSON format within SQLite databases, which is useful when data is complex and lacks a defined structure. The author explains that JSON virtual columns are defined using appropriate SQLite functions, and their proper use can significantly increase the speed of operations on this data. An important aspect covered in the article is the indexing of these columns, which enables even faster data querying. Indexes in SQLite can be created based on values from virtual columns, which is particularly beneficial when searching for specific values among complex JSON data. Finally, the article encourages testing virtual columns in your projects and demonstrates specific use cases that can bring considerable benefits when working with databases.
