Introduction OutOfMemoryException (often seen as java.lang.OutOfMemoryError) is one of the most frustrating problems Java developers face in production. When this happens inside a Hazelcast cluster, the impact becomes even more serious nodes crash, data partitions get redistributed, performance drops, and entire applications may become unstable. Hazelcast unlike a in memory data grid, it is fast […]
In today’s advanced digital world, APIs are the most used modern applications, with mobile apps fetching data to large-scale enterprise systems communicating across applications using microservices. Every millisecond is counted, and network reliability plays a critical role in delivering user-friendly features. However, there are multiple factors, network communication is never perfect. Sometimes the server takes
The Spring Framework is a widely used Java framework for building enterprise applications. It brings structure, scalability, and efficiency by using Dependency Injection(DI) and Inversion of Control(IOC) to simplify component wiring and lifecycle management. Two core concepts that often used by developers are @Bean and @Components, they may look similar, but their purposes and internal
Overview In contemporary AI and ML environments, vectors are the primary way to encode and search complex, high-dimensional data such as text, images, audio, and user preferences. Starting with Hazelcast 5.4, Vector Collections let developers implement semantic search, recommendation engines, and other AI features directly inside a distributed in-memory data grid, removing the need for
Overview gRPC is a high-performance open-source remote procedure call framework, initially it was developed by Google. It is to eliminate the boilerplate code and connect with services in and across the data center. The gRPC API uses the Protocol Buffers, it uses the protec compiler to generate source code in different supported languages. gRPC services
Overview In today’s data-driven world, managing large datasets efficiently is crucial for any application. Hazelcast, a powerful in-memory data grid, provides developers with a robust solution for handling distributed data effectively. Among its many features, Hazelcast Paging Predicates play a pivotal role in efficiently retrieving and processing data subsets. This article delves deep into the
Overview Hazelcast SQL stands out as a robust tool for querying distributed data structures like maps using SQL-like syntax. For developers looking to maximize the efficiency of their distributed systems, understanding how to use SQL predicates in Hazelcast is crucial. In this article, we delve deep into Hazelcast SQL predicates, explaining their significance, how to
Overview gRPC is a high-performance RPC framework developed by Google, enabling efficient communication between services in different programming languages. One of its standout features is bidirectional streaming, allowing both the client and server to send a sequence of messages to each other. This guide will help you set up and implement gRPC bidirectional streaming in
Overview gRPC Unidirectional Streaming in Java allows a server to continuously send multiple responses to the client after receiving a single request. The connection remains open, and the client can process the incoming stream of messages in real-time. This type of streaming is highly efficient for real-time systems, such as monitoring applications, chat services, or
