## Full Agenda:

18:30 - Building a bulletproof Kafka consumer in NodeJs
By Shai Moria SRE team lead & Keren Finkelstein tech lead @ Zooz (PayU)

In this talk, we will share with you our experiences & failures while building Kafka consumers in NodeJs.
How can we recover from a large lag in a consumer group?
How do we handle slow consumers and how can we recover from failures?
We will build with you our recipe for a bulletproof consumer and cover some interesting tradeoffs and decision-making through visibility and code examples.

19:10 - How do search engine crawlers work? And what can we learn from them?
By Ziv Kalderon Engineering Team Lead @ ActiveFence

Crawlers are the backbone of search engines. Without them, we would never be able to find up-to-date content on the web. In this talk, we will understand their underlying logic, implement crawlers using two different techniques (in node.js!), and will cover useful tips for successful crawling.
