如果您想要以下列支援的格式直接將數據複製到 Azure Data Lake Storage Gen2,您可以針對 Azure Data Lake Storage Gen2 帳戶建立具有 SAS 驗證的 Azure Blob 記憶體連結服務,以避免使用 Snowflake 的分段複製。 接收數據格式為Parquet、分隔文字或JSON,具有下列設定: 針對Parquet 格式,壓縮編解碼器為 None、 Snappy...
同时,我们也借鉴了 Snowflake 的集群优点,以增强分布式计算能力。综合了这些优点后,我们选择了 Rust 语言进行重新研发和实现。Databend 还有一个重大的的改进,我们把每一个功能层都做了微服务化,这样它的架构大概是: 图片 然而,Databend 的设计过程中也充满了挑战,因为云原生数仓的设计与传统数仓的设计有着显著的...
(Google BigLake —来自:THENEXTPLATFORM[1]) 虽然大多数数据仓库、数据湖或它们的混合物通常在其原始云环境中具有优势,例如 AmazonRedshift 或 Azure Synapse Analytics,或者在 Snowflake 的情况下,它可以在任何大型云端上,谷歌现在通过 BigLake 成功提供了独立于平台的数据分析环境。在这里,你可以使用数据仓库技术 ...
The difference between a data warehouse and a data lake is that a data lake stores data in its natural format, often blobs or files, while a data warehouse stores data as a database. Snowflake in brief Snowflake is a fully relational ANSI SQL data warehouse that was built from t...
