端口问题,HTTP协议(默认端口8123);TCP (Native)协议(默认端口号为9000),Python里的clickhouse_driver用的tcp端口9000,DBeaver使用的是HTTP协议所以可以使用8123端口。 ◼ 代码实现部分: (1)我们首先需要安装第三方库clickhouse_driver, (2)完整代码:使用clickhouse_driver 包中的Client类,其中需要修改的参数有host,us...
ClickHouse像ElasticSearch一样具有数据分片(shard)的概念,这也是分布式存储的特点之一,即通过并行读写提高效率。ClickHouse依靠Distributed引擎实现了Distributed(分布式)表机制,在所有分片(本地表)上建立视图进行分布式查询,使用很方便。 2.distribute表引擎介绍 Distributed表引擎是一种特殊的表引擎,自身不会存储任何数据,而是...

2. 如果你涉及大量group by这种聚合查询,用clickhouse。它的性能极高,单机单节点,在4亿数据里面聚合查询,结果秒出。你100亿数据,用三台机器部署clickhouse就够了。 不过他们都有短板。elasticsearch不适合复杂的聚合查询。clickhouse不适合频繁更新已有数据。有时候可能要两个结合起来用。
