Document Content and Description Below

Database Storage(Layer 3) Responsible - Data loaded into snowflake is reorganized into internal optimized/compressed/columnar format - Data objects stored by Snowflake are not directly visible nor ... accessible by customers - Manages all aspects of data(size,compression etc) Query Processing(Layer 2) Queries are processed using Virtual Warehouses - Each warehouse is an MPP compute cluster composed of compute nodes - Each warehouse is independent compute cluster that does no share compute resources Cloud Services(Layer 1) Services Include - Authentication - Infrastructure management § Metadata management § Query parsing and optimization § Access Control How are costs accumulated in Snowflake? - Based on Storage and compute resources used - Storage based on amount compressed data - Data retained for data recovery features - How big and long warehouse runs Snowflake is compliant with? - HIPPA - PCI DSS - SOC 1 - SOC 2 - FedRAMP Other factors that determine costs? - Region - On Demand Account - Capacity Account What is an On Demand account? Usage-based pricing with no long term licensing requirements What is an Capacity account? Discounted pricing based on an up-front capacity commitment VPS(Virtual Private Snowflake) accounts have different? Naming Conventions which results in different hostnames/URLs used to access VPS accounts Snowflake Connector Ecosystem scales what industries? -Data Integration - Business Intelligence (BI) - Machine Learning & Data Science - Security & Governance - SQL Development & Management - Programmatic Interfaces(Python, JavaScript) What is a database? Logical grouping of schemas What is a schema? Grouping of database objects, such as: - Tables - Views What is a partition? A partition is a unit of management that is manipulated independently using specialized DDL and syntax What is a micro-partition? Contiguous units of storage - 50 MB and 500 MB of uncompressed data(Snowflake data is compressed though) Snowflake stores metadata about partitions such as? - The range of values for each of the columns in the micro-partition. - The number of distinct values. What is Data Clustering in Snowflake? As data is inserted/loaded into a table, clustering metadata is collected and recorded for each micro-partition created during the process. Snowflake then leverages this clustering information to avoid unnecessary scanning of micro-partitions What is data clustering? Essentially, is how data is sorted. Metadata for clustering contains? - Total number of micro-partitions that comprise the table. - Number of micro-partitions containing values that overlap with each other (in a [Show More]
