数据表水平分区在所有节点上,每个节点负责存储在本地磁盘的部分 rows。这个设计对星形模型很友好,广播维度表需要带宽很小、事实表以分区形式存在本地。因为没有共享数据结构,不存在硬件资源的竞争,所以不需昂贵的定制硬件。 在纯shared-nothing 架构中,每个节点有相同的职责,运行在相同的硬件上。所以,软件很优雅,...

1. Update the rows in the target table with new data (with the same keys). Then insert new rows from the intermediate or landing table that are not in the final table. UPDATE oracle_target_table t SET t.value = s.value FROM landing_delta_table in WHERE t.id = in.id; ...
You can use the search optimization service to improve query performance. For details, see Search Optimization Service.Working with Joins A join combines rows from two tables to create a new combined row that can be used in the query. Learn join concepts, types of joins, and how to work wi...
A predicate is an expression in theWHEREclause of a SQL query that evaluates to a Boolean value and filters rows based on multiple conditions. The Athena Snowflake connector can combine these expressions and push them directly to Snowflake for enhanced functionality and to reduce the amount of ...
To improve the clustering of the underlying table micro-partitions, you can always manually sort rows on key table columns and re-insert them into the table; however, performing these tasks could be cumbersome and expensive. Instead, Snowflake supports automating these tasks by designating one or...
