海量日志数据存储用 elasticsearch 和 hbase 哪个好？

Answer 1

HBase是schema free的，加字段完全没问题
用ES存日志数据，成本会很高
推荐的架构：ES给日志建索引（看业务是否需要），日志原始内容存HBase

Answer 2

elasticsearch 和 hbase 存储机制不一样

hbase是Key vlaue 的形式，大批量拉取数据，存储海量的数据性能必须大于elasticsearch，但是搜索列没有优势

elasticsearch是基于lunce,优点是搜索速度快，方便建立索引，支持全文检索，但是数据上百亿的情况下，干不过HBASE

两者都有好处，使用场景不一样
