Query: A Survey on Deep Reinforcement Learning for Data Processing and
  Analytics   Data processing and analytics are fundamental and pervasive. Algorithms play
a vital role in data processing and analytics where many algorithm designs have
incorporated heuristics and general rules from human knowledge and experience
to improve their effectiveness. Recently, reinforcement learning, deep
reinforcement learning (DRL) in particular, is increasingly explored and
exploited in many areas because it can learn better strategies in complicated
environments it is interacting with than statically designed algorithms.
Motivated by this trend, we provide a comprehensive review of recent works
focusing on utilizing DRL to improve data processing and analytics. First, we
present an introduction to key concepts, theories, and methods in DRL. Next, we
discuss DRL deployment on database systems, facilitating data processing and
analytics in various aspects, including data organization, scheduling, tuning,
and indexing. Then, we survey the application of DRL in data processing and
analytics, ranging from data preparation, natural language processing to
healthcare, fintech, etc. Finally, we discuss important open challenges and
future research directions of using DRL in data processing and analytics.
