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: 遇到Memory limit (for query)超限报错说明是查询内存占用过多(实例总内存的70%)导致失败,这种情况下您需要垂直升配提高实...
在进行group by的时候，内存使用量已经达到了max_bytes_before_external_group_by的时候就进行写磁盘(基于磁盘的group by相对于基于磁盘的order by性能损耗要好很多的)，一般max_bytes_before_external_group_by设置为max_memory_usage / 2，原因是在clickhouse中聚合分两个阶段：查询并且建立中间数据；合并中间数据 ...

解决:升级clickhouse-jdbc 驱动jar或者pom引入依赖版本到0.2.6 。 3)Code: 159,read timeout 原因:查询超时导致报错。 解决:执行某些SQL很耗时导致最后报错读超时,这是因为clickhouse执行单次SQL的默认最大等待时间是30s,如果有比较耗时的SQL, 可以通过将JdbcURL的socket_timeout参数值设置的大一点来解决这个问题(注...
