Query: Data Management in Microservices: State of the Practice, Challenges, and
  Research Directions   Microservices have become a popular architectural style for data-driven
applications, given their ability to functionally decompose an application into
small and autonomous services to achieve scalability, strong isolation, and
specialization of database systems to the workloads and data formats of each
service. Despite the accelerating industrial adoption of this architectural
style, an investigation of the state of the practice and challenges
practitioners face regarding data management in microservices is lacking. To
bridge this gap, we conducted a systematic literature review of representative
articles reporting the adoption of microservices, we analyzed a set of popular
open-source microservice applications, and we conducted an online survey to
cross-validate the findings of the previous steps with the perceptions and
experiences of over 120 experienced practitioners and researchers.
  Through this process, we were able to categorize the state of practice of
data management in microservices and observe several foundational challenges
that cannot be solved by software engineering practices alone, but rather
require system-level support to alleviate the burden imposed on practitioners.
We discuss the shortcomings of state-of-the-art database systems regarding
microservices and we conclude by devising a set of features for
microservice-oriented database systems.
