mysql/mariadb<oltp> as olap: 缺少hash join和parallel 复杂的SQL查询,只会有一个CPU正在满负荷地运转 方案选型了以后，只能做更多的优化 尽量使用主键查询 选择索引的字段，一定要符合差异率高的字段 在group by后面使用order by null，禁用默认的group by排序 手动拆分SQL，再合并结果集 my.cnf配置优化，增加临时表空间和key_buffer_size mariadb columnstore (InfiniDB olap store engine) 大数据离线分析 大规模分布式并行（MPP架构） 高性能 压缩 列式 (对比非开源mysql数据仓库系统Infobright) columnstore:三层架构 用户模块 User Module：Execution Manager／DMLProc／DDLProc 性能模块 Performance Module：n*Performance Module 数据存储层 Data Storage: 本地磁盘(local disks)/共享存储(SAN)/分布式存储(EBS/HDFS/GlusterFS) columnstore docker install(基于centos的docker): git clone https://github.com/mariadb

Can I have Eloquent ORM run a query without using prepared statements? Or do I have to use whereRaw() ? I need to use a raw query because I'm trying to interact with InfiniDB, which lacks support for prepared statements from PHP. At any rate, all queries will be using internally generated data, not user input so it should not be a security issue. For anything other than SELECT you can use unprepared() DB::unprepared($sql); For an unprepared SELECT you can use plain PDO query() by getting access to active PDO connection through getPdo() $pdo = DB::getPdo(); $query = $pdo->query($sql); $result =
