Presentation at NetPonto community: "We’re going to discuss gRPC, Google’s open-source RPC framework. I’ll dive a bit into the history of RPC as a protocol, and what its historical use has been. I’ll also highlight some benefits to adopt gRPC and how its possible to swap out parts of gRPC and still take advantage of gRPC’s benefits. Finally I’ll answer the question that has been on many lips since
RocksDB is an embedded key-value store written in C++ and optimized for fast storage environments like flash or RAM. It uses a log-structured merge tree to store data by writing new data sequentially to an in-memory log and memtable, periodically flushing the memtable to disk in sorted SSTables. It reads from the memtable and SSTables, and performs background compaction to merge SSTables and remov
This document introduces AMQP messaging using RabbitMQ as a broker. It explains that AMQP and RabbitMQ allow applications to communicate asynchronously by sending and receiving messages through a broker, providing decoupling, queueing, load balancing and scalability. It provides details on RabbitMQ as an open source AMQP broker developed by Rabbit Technologies and the AMQP Working Group which main
Devoxx 2012 talk by Jaromir Hamala, C2B2 Senior Consultant. The Garbage-First (G1) is the latest garbage collector in the JVM, aiming to be the long-term replacement for CMS. Targeted for machines with large memories and multiple processors. Promising low and more predictable pause times while achieving high throughput. The session will introduce the architecture and design of G1. Then the main fo
This document summarizes a microservices meetup hosted by @mosa_siru. Key points include: 1. @mosa_siru is an engineer at DeNA and CTO of Gunosy. 2. The meetup covered Gunosy's architecture with over 45 GitHub repositories, 30 stacks, 10 Go APIs, and 10 Python batch processes using AWS services like Kinesis, Lambda, SQS and API Gateway. 3. Challenges discussed were managing 30 microservices, ensur
The document discusses four physical memory models in Linux: flat memory model, discontinuous memory model, sparse memory model, and sparse memory virtual memmap. It describes how each model addresses physical memory (page frames) and maps them to page descriptors. The sparse memory model is currently used, using memory sections to allocate page structures and support memory hotplug. It initialize
In this webinar Hazelcast has pushed the In-Memory Data Grid category further by adding High-Density Caching and making great strides in performance – but what’s next? In this talk Hazelcast CEO Greg Luck will explain the direction of the Hazelcast platform in detail. He’ll share what’s planned for features of High-Density Caching as well for the In-Memory Computing platform at large in the areas
