Database Indexing and Query Processing (Dagstuhl Seminar 22111)

The Dagstuhl Seminar 22111 on "Database indexing and query processing", held from March 13 to March 18 2022, brought together researchers from academia and industry to discuss robustness in database management systems. This seminar was a continuation of previous seminars on the topic of Robust Query Processing, where we included indexing as a general topic and also discussed aspects that have not been addressed by the previous instances of the seminar. This article summarizes the main discussion topics, and presents the summary of the outputs of three work groups that discussed: i) storage architectures, ii) robust operators, and iii) indexing for data warehousing.
