If the table schema changes, both the FE node version and SE version need to be updated. If the FE node version and SE version are inconsistent with the schema version, schema latency may occur. If a large number of DDL statements are executed on the partitioned parent table, the ...
Two users might be pointing to different objects in the same database, resulting in different execution plans. Schema changes (usually changes in indexes) between the two operations. 12.1.1.2 Different Costs Even if the schemas are the same, the optimizer can choose different execution plans when...

Wait schema cost:存储引擎(Storage Engine,SE)和Frontend(FE)对齐Schema版本所耗时间。当表的Schema发生变化时,FE会更新节点版本,同理SE也会更新节点版本,如果FE和SE的版本不对齐,则会出现Schema延迟。如果延迟较高,一般原因是因为SE处理慢,尤其是分区父表的DDL较多时,延迟较高,导致数据写入/查询慢,建议针对性优化...
