以上的这些弹性、隔离等等其实在我看来都是锦上添花的特性,核心还是在于计算引擎要快,但是这里 Snowflake 没有什么亮点,和其他很多数据库引擎类似的。具有以下几点特征: 列式存储,好处是方便压缩、查询过滤,以及利于 CPU Cache 和 SIMD 向量化,充分利用 CPU 的并行计算能力,减少了中间结果的 IO 基于Push,这一点可...

These universal principles have helped guide database design for decades, and this book pairs them with unique Snowflake-native objects and examples like never before – giving you a two-for-one crash course in theory as well as direct application. By the end of this Snowflake book, you’...
Nowadays, data is one of the main assets of any company. As a result, each team of analysts is faced with the need to organize data science processes. Snowflake is a smart choice as a data source for storing structured and semistructured data.
Materialized views:Materialized views can serve as a type of cache for frequently queried data. Snowflake can now manage this cached data so that BI tools or metrics layers are able to access live data. Previously, they had to periodically extract the data and materialize it outside the data...

Auto Cache - Maintain an automatic local cache of data on all requests. The provider will automatically load data into the cache database each time you execute a SELECT query. Each row returned by the query will be inserted or updated as necessary into the corresponding table in the cache da...
