Updatable learned index with precise positions [PDF]
Proceedings of the VLDB Endowment, 2021 Index plays an essential role in modern database engines to accelerate the query processing. The new paradigm of "learned index" has significantly changed the way of designing index structures in DBMS. The key insight is that indexes could be regarded as learned models that predict the position of a lookup key in the dataset.
