Aerospike: Up and Running. Developing on a Modern Operational Database for Globally Distributed Apps

Aerospike: Up and Running. Developing on a Modern Operational Database for Globally Distributed Apps - Opis

If you're a developer looking to build a distributed, resilient, scalable, high-performance application, you may be evaluating distributed SQL and NoSQL solutions. Perhaps you're considering the Aerospike database.This practical book shows developers, architects, and engineers how to get the highly scalable and extremely low-latency Aerospike database up and running. You will learn how to power your globally distributed applications and take advantage of Aerospike's hybrid memory architecture with the real-time performance of in-memory plus dependable persistence. After reading this book, you'll be able to build applications that can process up to tens of millions of transactions per second for millions of concurrent users on any scale of data.This practical guide provides:Step-by-step instructions on installing and connecting to AerospikeA clear explanation of the programming models availableAll the advice you need to develop your Aerospike applicationCoverage of issues such as administration, connectors, consistency, and securityCode examples and tutorials to get you up and running quicklyAnd more Spis treści:
