Abstrak

The paper discusses the authors' perspectives and insights on building autonomous data services on the Microsoft Azure cloud platform. It highlights the key challenges and opportunities presented by the cloud in enabling the development of such autonomous services.
The authors outline three key viewpoints:

The economic scale of the cloud has necessitated the development of autonomous data services, and the cloud is a necessary precondition for achieving true autonomy in data services.
Autonomy spans all layers of data services, including the cloud infrastructure layer, query engine layer, and service layer, and the interactions among these layers must be considered.
The objectives of autonomous data services are to improve ease of use, optimize performance, reduce costs, and maintain data privacy.

The paper then discusses the authors' progress and lessons learned in automating various aspects of data services at different layers:
Cloud Infrastructure Layer:

Modeling system behaviors based on domain knowledge and system metrics
Modeling user behaviors to balance quality of service and cost
Query Engine Layer:

Workload analysis to learn from past workloads
Enhancing query optimization with learned components
Improving query execution through checkpoint optimization
Leveraging computation reuse across recurring queries and pipelines
Service Layer:

Automating customer-facing decisions and options using individual, segment, and global models
Transferring learning across customers and applications
The paper also outlines future directions, including the importance of reusability, standardization, joint optimization across components, and responsible AI practices.

Statistik

Over 60% of jobs in SCOPE are recurring, and nearly 40% of daily jobs share common subexpressions with at least one other job.
Deploying the checkpoint optimizer in Cosmos freed up to 70% of temporary storage on hotspots and reduced job restart time by 68% on average.
Deploying the CloudViews computation reuse solution on Cosmos resulted in a 34% improvement in accumulative job latency and a 37% reduction in total processing time.
For PostgreSQL and MySQL servers, a simple heuristic that predicts the load of a server based on the previous day achieved 96% accuracy.

Kutipan

"The economic scale that has driven the adoption of cloud technology has also necessitated the development of autonomous data services. However, we contend that true autonomous data services can only be achieved in the cloud, meaning that the cloud is a necessary precondition for the attainment of autonomy in data services."
"Autonomy spans all layers of data services: cloud infrastructure layer, query engine layer, and service layer."
"The objectives of autonomous data services are: improving ease of use, optimizing performance, reducing costs, and maintaining data privacy."

What are the potential challenges and trade-offs in jointly optimizing multiple components of a data service, and how can they be effectively addressed

Jointly optimizing multiple components of a data service presents several potential challenges and trade-offs that need to be addressed effectively:

Complexity: Optimizing multiple components simultaneously can introduce complexity, especially when considering the interactions and dependencies between different parts of the system. Managing this complexity and ensuring that optimizations do not conflict with each other is crucial.

Resource Allocation: Allocating resources for joint optimization can be challenging, as different components may have varying resource requirements. Balancing resource allocation to ensure optimal performance across all components is essential but can be resource-intensive.

Performance Trade-offs: Optimizing one component may inadvertently impact the performance of another component. Trade-offs between different optimization strategies need to be carefully evaluated to achieve overall system efficiency without sacrificing individual component performance.

Coordination and Communication: Effective coordination and communication between teams responsible for different components are essential for successful joint optimization. Ensuring alignment on optimization goals, strategies, and timelines is critical to avoid conflicts and streamline the optimization process.

To address these challenges, a holistic approach to optimization is required, involving thorough planning, clear communication, and continuous monitoring of system performance. By establishing clear objectives, defining optimization strategies, and fostering collaboration among teams, the potential trade-offs can be mitigated, and the benefits of joint optimization can be realized effectively.
