ClickHouse是一个OLAP数据库,它在单表查询方面的速度优于关联查询,而且与其他OLAP数据库相比,这种差距更为明显。然而,ClickHouse也有一些限制,比如没有完整的事务支持,缺少高频率、低延迟的修改或删除已存在数据的能力,只能用于批量删除或修改数据。此外,ClickHouse的稀疏索引使得它不适合通过键检索单行的点查询。\[1\]
关于ClickHouse的文件存储位置,配置文件位于/etc/clickhouse-server/config.xml,启动文件位于/usr/bin,数据存储在/var/lib/clickhouse,日志存储在/var/log/clickhouse-server。\[2\]
如果你想下载ClickHouse,可以在http://repo.red-soft.biz/repos/clickhouse/stable/el7/找到下载地址。在单机模式下安装ClickHouse,你需要上传5个文件到/usr/local/clickhouse目录,并分别安装这5个rpm文件。然后,你可以启动ClickServer。\[3\]
