[Hadoop] Elasticsearch调优实践.pdf

说明： Elasticsearch（ES）作为NOSQL+搜索引擎的有机结合体，不仅有近实时的查询能力，还具有强大的聚合分析能力。因此在全文检索、日志分析、监控系 统、数据分析等领域ES均有广泛应用。而完整的Elastic Stack体系（Elasticsearch、Logstash、Kibana、Beats），更是提供了数据采集、清洗、存储、 可视化的整套解决方案。 本文基于ES 5.6.4，从性能和稳定性两方面，从linux参数调优、ES节点配置和ES使用方式三个角度入手，介绍ES调优的基本方案。

[算法与数据结构] Towards Robust Distributed Systems.pdf

说明： Current distributed systems, even the ones that work, tend to be very fragile: they are hard to keep up, hard to manage, hard to grow, hard to evolve, and hard to program. In this talk, I look at several issues in an attempt to clean up the way we t

[算法与数据结构] Perspectives on the CAP Theorem.pdf

说明： Almost twelve years ago, in 2000, Eric Brewer introduced the idea that there is a fundamental trade-off between consistency, availability, and partition tolerance. This trade-off, which has become known as the CAP Theorem, has been widely discussed
