Design a Real-Time Logging and Telemetry System
Design a robust, scalable, and real-time logging and telemetry system suitable for a large application platform.
Core Requirements
- Event Producers: The system must support a multitude of services sending log and metric events.
- Asynchronous Submission: Event submission from producer services should be asynchronous to minimize impact on their primary operations.
- Real-time Querying: Users must be able to read and query recently ingested data in real-time for purposes such as debugging, monitoring, and dashboard visualization.
Key Discussion Areas
Candidates should be prepared to discuss the following aspects of their design:
- APIs and Data Model: Define the interfaces for event submission and querying, along with the underlying data structures.
- High-Level Architecture: Outline the overall system architecture, covering ingestion, storage, and querying components.
- High Write Throughput: Detail strategies for handling and sustaining a very high volume of incoming write operations.
- Real-time Read Availability: Explain mechanisms to ensure recently ingested data is immediately available for querying.
- Reliability and Fault Tolerance: Address how the system will maintain availability and data integrity in the face of failures.
- Backpressure: Describe how the system will manage situations where ingestion rates exceed processing capacity.
- Scaling and Data Management: Discuss approaches to partitioning, indexing, data retention policies, and the trade-offs involved in scaling the system.

Core dilemma
Balancing extremely high, bursty write throughput for log/metric events with the requirement for near real-time queryability of recently ingested data, all while ensuring reliability, fault tolerance, and cost-effectiveness at scale.
