JSON tiles accelerate analytics on flexible JSON data

db.cit.tum.de Editor score 7/10

JSON tiles detect important keys, extract them for relational queries, and collect statistics for the optimizer while supporting changing schemas. The paper reports scan performance similar to columnar storage, a useful approach for semi-structured data systems.

What: JSON tiles let relational systems analyze flexible JSON data without losing its schema flexibility.
Method: They detect and extract important keys, handle heterogeneous or changing data, and collect statistics that help the query optimizer choose execution plans.
Why it matters: The method aims to bring JSON analytics closer to native relational speed without requiring a fixed schema upfront.

JSON tiles provide statistics to the optimizer, which selects plans for relational database systems. Sketched from the article's own text.
