Meet Nicolas Frankel at JavaDay Lviv 2024 Offline Part Tracking a request's flow across different components in distributed systems is essential. With the rise of microservices, their importance has risen to critical levels. Some proprietary tools for tracking have been used already: Jaeger and Zipkin naturally come to mind. Observability is built on three pillars: logging, metrics, and tracing. OpenTelemetry is a joint effort to bring an open standard to them. Jaeger and Zipkin joined the effort so that they are now OpenTelemetry compatible. In this talk, I'll describe the above in more detail and showcase a (simple) use case to demo how you could benefit from OpenTelemetry in your distributed architecture.

A project we worked on with the University of Warsaw is a library that makes it easy to develop #Rustlang applications that consume data from a #ScyllaDB Change Data Capture Log. Gor Stepanyan shares how this collaboration led to a new Rust library that is faster than its #Golang counterpart (and uses less CPU). #NoSQL #database #streamingdata

🔍 Ever wondered why Elasticsearch is lightning-fast at text searches? The secret sauce lies in the inverted index! 🥇 Elasticsearch uses an inverted index, a data structure that maps each term to the documents it appears in, allowing for rapid retrieval of relevant documents without scanning through all of them. ⚡📄 To rank the results, Elasticsearch uses something known as term frequency (TF) and inverse document frequency (IDF). Combining TF and IDF, Elasticsearch ensures the most relevant documents appear first in your search results. 🏆📊 Want to learn Elasticsearch and the inverted index in detail? Check out this 2-minute read to get all the insights! 📖✨ https://lnkd.in/eGue-8uS #Systemdesign #SystemDesignInterview #Coding #Interviewtips #ElasticSearch #BigData #SearchEngines
