Here are the key points about GRASP patterns:
1. GRASP stands for General Responsibility Assignment Software Patterns. It is a set of 9 patterns used to assign responsibilities to classes in object-oriented design.
2. Properly assigning responsibilities and distributing them among classes is a core part of object-oriented design. Developers and designers should be familiar with these patterns.
3. The 9 GRASP patterns are: Information Expert, Creator, Controller, Low Coupling, High Cohesion, Indirection, Polymorphism, Pure Fabrication, and Protected Variations. Each pattern provides guidance on distributing responsibilities in a certain context.
4. When designing a system, analyzing which classes should have which responsibilities based
Spring Boot Actuator 2.0 & Micrometer #jjug_ccc #ccc_a1Toshiaki Maki

Spring Boot Actuator 2.0 provides additional monitoring endpoints for Spring Boot applications running in production. Micrometer allows instrumenting Spring Boot applications without vendor lock-in by providing common metrics that can be exported to systems like Prometheus, Datadog, and Cloud Foundry Metrics. Key features include multi-dimensional metrics with tags instead of hierarchies, histograms for response time distributions, and client-side percentiles. Monitoring of Spring Boot applications can be done on Cloud Foundry by scraping the /actuator/prometheus endpoint across application instances behind a load balancer.

Managing multiple event types in a single topic with Schema Registry | Bill B...HostedbyConfluent
?
With Apache Kafka, it's typical to place different events in their own topic. But different event types can be related. Consider customer interactions with an online retailer. The customer searches through the site and clicks on various items before deciding on a final purchase. But businesses can gain insight by processing these events in sequence. Using the event type per topic leaves a lot of work for developers. Is there a better way?
Fortunately, there is. Schema Registry now supports having multiple event types in the same topic. By placing various event types in a single topic, you can now handle different related events in-order. In this presentation, I'll introduce Schema Registry then we'll dive into how it handles multiple event types in a single topic, including examples.
You will learn how and when to apply the multiple event types per topic pattern. Additionally, you'll learn how schema references work in Schema Registry.

The document discusses the architecture and performance optimization techniques used in IntelliJ IDEA. It describes the component model, services, file system synchronization, indexing framework, program source interface (PSI), background analysis, and multi-core support. It also provides tips for optimizing performance related to the system, JVM, IDE settings, and reporting performance issues.
