在ClickHouse中,错误代码241代表Memory limit (total) exceeded,意味着查询尝试使用的总内存量超过了配置的限制。这通常发生在处理大型查询或数据聚合时,ClickHouse为了避免耗尽所有可用内存资源而强制终止这些查询。 导致ClickHouse出现241错误码的可能原因 查询设计不当: 复杂的聚合查询或连接(JOIN)操作可能会消耗大量内存...
阿里云云数据库ClickHouse执行查询任务时,实例内存升高,提示类似以下错误: Memory limit (for query) exceeded Memory limit (for total) exceeded 问题原因 实例内存升高的原因如下: 查询内存占用过多 实例总内存使用超限 解决方案 ClickHouse服务端对所有查询线程都配有memory tracker,同一个查询下的所有线程tracker会汇...
一般使用clickhouse查询，数据量较大的时候，通常会出现如下错误：Memory limit (total) exceeded: would use 6.86 GiB (attempt to allocate chunk of 4196472 bytes), maximum: 6.86 GiB:这说明查询已经超过最大内存限制，导致查询失败。可以通过参数max_memory_usage来进行设置，提高内存上限。类似的还有很多。Cl...
ClickHouse version: 22.3.3.44 Machines Memory: 62G OS: CentOS 7.6.1810 Hello! I often receive this error during the time when I use ck. I thought it could be solved by setting max_server_memory_usage, but it didn't work. I feel that the 275.91 PiB reported error is very strange. Ha...
含义:限制ClickHouse服务器节点的总RAM使用量 默认值: 0 默认情况下的计算公式如下: max_server_memory_usage = memory_amount(内存总量) * max_server_memory_usage_to_ram_ratio(占比分数值) 3.max_server_memory_usage_to_ram_ratio 含义:定义可用于Clickhouse服务器的总物理RAM量的一部分。如果想要服务器利...
