Event Streaming- Event streaming in Java is a programming concept where data is continuously generated, processed, and consumed as a stream of events in real-time

Skills to look for :

- Apache Kafka, Apache Pulsar, RabbitMQ. Among this, BLK majorly uses Apache.

- Distributed Caching- Distributed caching in Java is a technique to store data in memory across multiple servers or nodes to improve application performance, scalability, and availability. It is commonly used in systems where frequent access to the same data is required, such as web applications, APIs, and microservices.

Skills to look for :

- Apache ignite. Knowledge in data structures- one of these-> Least Recently Used Cache(LRU,Least Frequently sued cache(LFU), Time to Live(TTL)

Concurrent Apps :

- Concurrent applications in Java are designed to execute multiple tasks simultaneously, making efficient use of modern multi-core processors.

Skills to look for : Streams and Parallel Streams, Executor Framework, concurrent collections.

Building Scalable services Skills to look for in resume-Multithreading, JVM Tuning, SOLID principles, Design patterns-(Singleton, Factory, Builder), SQL
