HOW CANVA IMPLEMENTED END-TO-END TRACING

Canva has implemented end-to-end distributed tracing for observability in their systems. They emphasize the Three Pillars of Observability: logs (timestamped events), metrics (quantifiable statistics), and traces (representation of request events). With distributed tracing, they use traces, spans (single operations within a trace), and tags (metadata key-value pairs) to gain insights into their system's performance. Canva also developed a custom frontend tracing SDK for themselves.

WHY TIERED STORAGE FOR APACHE KAFKA IS A BIG THING

Apache Kafka has introduced Tiered Storage, which allows for the separation of compute and storage. This article explores the architecture, use cases, benefits, and even presents a case study of storing petabytes of data in the Kafka commit log. Tiered Storage optimizes storage resources by using different storage tiers based on data access patterns, performance requirements, and cost considerations.
