11、 Memory Limit Exceeded for Query 作为一个新用户,ClickHouse经常看起来像魔术一样——每个查询都非常快,即使是在最大的数据集和最复杂的查询上。而且,很多人甚至会通过各种变态的查询来测试ClickHouse的极限。超出内存的查询可能是由多种原因造成的。 最常见的是,我们在高基数字段上看到大型join或聚合。如果性能...

当使用Flink向ClickHouse批量持续写入数据时,遇到如下的错误信息: Caused by: java.sql.SQLException: Code: 241, e.displayText() = DB::Exception: Memory limit (total) exceeded: would use 6.86 GiB (attempt to allocate chunk of 4295130 bytes), maximum: 6.86 GiB (version 20.8.3.18) , server ...
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。Clickhouse提供了大量的参数配置，例如:一般常用的主要有以下几种：1...

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会汇报给一个memory tracker for query,再上层还是memory tracker for total。您可以根据情况采取如下解决方案: ...
