海外TECH	DEV Community	Snowflake Zero Copy Clone 101 - An Essential Guide 2023	https://dev.to/chaos-genius/snowflake-zero-copy-clone-101-an-essential-guide-2023-hpg	Snowflake Zero Copy Clone An Essential Guide IntroductionSnowflake zero copy clone is an incredibly useful and advanced feature that allows users to clone a database schema or table quickly and easily without any additional Snowflake storage costs What s more it takes only a few minutes for Snowflake zero copy clone to complete without the need for complex manual configuration as often done in conventional databasesーdepending on the size of the source item This article covers all you need to know about Snowflake zero copy clone Let s dive in What is Snowflake zero copy clone Snowflake zero copy clone often referred to as cloning is a feature in Snowflake that effectively creates an exact copy of a database table or schema without consuming extra storage space taking up additional time or duplicating any physical data Instead a logical reference to the source object is created allowing for independent modifications to both the original and cloned objects Snowflake zero copy cloning is fast and offers you maximum flexibility with no additional Snowflake storage costs associated with it Use cases of Snowflake zero copy cloneSnowflake zero copy clone provides users with substantial flexibility and freedom with use cases like To quickly perform backups of Tables Schemas and Databases To create a free sandbox to enable parallel use cases To enable quick object rollback capability To create various environments e g Development Testing Staging etc To test possible modifications or developments without creating a new environment Snowflake zero copy clone provides businesses with smarter faster and more flexible data management capabilities How does Snowflake zero copy clone work The Snowflake zero copy clone feature allows users to clone a database object without making a copy of the data This is possible because of the Snowflake micro partitions feature which divides all table data into small chunks that each contain between and MB of uncompressed data However the actual size of the data stored in Snowflake is smaller because the data is always stored compressed When cloning a database object Snowflake simply creates new metadata entries pointing to the micro partitions of the original source object rather than copying it for storage This process does not involve any user intervention and does not duplicate the data itselfーthat s why it s called zero copy clone To gain a better understanding let s deep dive even further To illustrate this consider a database table EMPLOYEE table and its cloned snapshot EMPLOYEE CLONE in a Snowflake database The metadata layer in Snowflake connects the metadata of EMPLOYEE to the micro partitions in the storage layer where the actual data resides When the EMPLOYEE CLONE table is created it generates a new metadata set pointing to the same micro partitions storing the data for EMPLOYEE Essentially the clone EMPLOYEE CLONE table is a new metadata layer for EMPLOYEE rather than a physical copy of the data The beauty of this approach is that it enables us to create clones of tables quickly without duplicating the actual data saving time and storage space Moreover since the clone shares the same set of micro partitions as the original table any changes made to the data in one table will automatically reflect in the other In Snowflake micro partitions cannot be changed altered once they are created Suppose any modifications to the data within a micro partition need to be made In that case a new micro partition must be created with the updated changes the existing partition is maintained to provide fail safe measures and time travel capabilities For instance when data in the EMPLOYEE CLONE table is modified Snowflake replicates and assigns the modified micro partition M P to the staging environment updating the clone table with the newly generated micro partition M P and references it exclusively for the EMPLOYEE CLONE table thereby incurring additional Snowflake storage costs only for the modified data rather than the entire clone What are the benefits of Snowflake zero copy clone Snowflake zero copy clone feature offers a variety of beneficial characteristics Let s look at some of the key benefits Effective data cloning Snowflake zero copy clone allows you to create fully usable copies of data without physically copying the data significantly reducing the time required to clone large objects Saves storage space and costs It doesn t require the physical duplication of data or underlying storage and it doesn t consume additional storage space which can save on Snowflake costs Hassle free cloning It provides a straightforward process for creating copies of your tables schemas and databases using the keyword CLONE without needing administrative privileges Single source data management It creates a new set of metadata pointing to the same micro partitions that store the original data Each clone update generates new micro partitions that relate solely to the clone Data Security It maintains the same level of security as the original data This ensures that sensitive data is protected even when it s cloned What are the limitations of Snowflake zero copy clone Snowflake zero copy clone feature offers many benefits Still there are certain limitations to keep in mind Resource requirements and performance impact Cloning operations require adequate computing resources so excessive cloning can lead to performance degradation Longer clone time for large micro partitions Cloning a table with a large number of micro partitions may take longer although it is still faster than a traditional copy Unsupported Object Types for Cloning Cloning does not support all object types Which are the objects supported in Snowflake zero copy clone Snowflake zero copy clone feature supports cloning of the following database objects DatabasesSchemasTablesViewsMaterialized viewsSequencesNote When a database object is cloned the clone is not similar to the source object rather the clone is a reference to the original object and modifications to the clone do not affect the source object The clone will contain a new set of metadata including a new set of access controls so the user must ensure that the appropriate permissions are granted for the clone How do access control works with cloned objects in Snowflake When using Snowflake s zero copy clone feature it s important to keep in mind that cloned objects do not automatically inherit copy privileges from the source object This means that an account admin ACCOUNTADMIN or the owner of the cloned object must explicitly grant any required privileges to the newly created clone If the source object is a database or schema the granted privileges of any child objects in the source will be replicated to the clone But in order to create a clone the current role must have the necessary privileges on the source object For example tables require the SELECT privilege while pipelines streams and tasks require the OWNERSHIP privilege and other object types require the USAGE privilege What are the account level objects not supported in Snowflake zero copy clone Snowflake zero copy clone doesn t support particular objects that cannot be cloned These include account level objects which exist at the account level Some examples of account level objects are Account level rolesUsersGrantsVirtual WarehousesResource monitorsStorage integrations ConclusionSnowflake zero copy clone feature provides an innovative and cost efficient way for users to clone tables without using additional Snowflake storage costs This process streamlines the workflow allowing databases tables and schemas to be cloned without creating separate environments This article provided an in depth overview of Snowflake zero copy clone from how it works to its potential use cases and demonstrated how to set up and utilize the feature In the next article we will cover how to clone a table in Snowflake Stay tuned	2023-05-10 06:10:18
