Product Information

Snowflake: The Definitive Guide” written by Joyce Kay Avila, a certified Snowflake and Data Superhero with more than 25 years of experience as a business and technology leader. She is currently the Snowflake practice manager for a Snowflake partner consulting firm. Discover how Snowflake’s unique objects and features can be used to leverage universal modeling techniques through real-world examples and SQL recipes By the end of this Snowflake book, you’ll have learned how to leverage Snowflake’s innovative features, such as time travel, zero-copy cloning, and change-data-capture, to create cost-effective, efficient designs through time-tested modeling principles that are easily digestible when coupled with real-world examples. What you will learn

What we now have created is a deep copy of the CUSTOMERS table and a new table, which has received all data from CUSTOMERS and is called CUSTOMERS_DEEP_COPY. The deep copy means that the table structure and data has been copied, as opposed to a shallow copy, which would copy the table structure only. This copied table is now an independent copy that can have a life cycle of its own with no changes or side effects originating from any operations performed on the CUSTOMERS table. A SELECT QUERY statement on this new table would generate the same results as shown in the previous table. Once you start saying yes, it’s very hard to say no. I’ve kissed so many boys that I don’t fancy just because I feel sorry for them.”

About Snowflake Books

this is another contemporary, coming of age tale which follows debbie, an 18 year old who lives on a dairy farm as she navigates her 1st year at university, while also trying to handle her eccentric and troubled mother and uncle. if you know me you know i love a coming of age story, so this premise was right up my street. the writing was beautiful and lyrical but also raw, perfectly capturing the mindset of what it’s like to be a young woman figuring out life and trying to survive university (perfect for fans of sally rooney and naosie dolan in that regard). it also had a small magical realism element related to dreams which i definitely think added something unique to the story, even though i do wish it was developed a bit more. i also really enjoyed the irish slang in the dialogue and the exploration of some of the folklore, i found it all so interesting to read about! nealon also touches on several themes in this book too, like mental illness, family dynamics, friendship, identity, alcoholism, the pressure of university, and more. As you progress through the chapters, you will leverage Snowflake's capabilities to process a series of SQL statements using tasks to build data pipelines and find out how you can create modern data solutions and pipelines designed to provide high performance and scalability. You will also get to grips with creating role hierarchies, adding custom roles, and setting default roles for users before covering advanced topics such as data sharing, cloning, and performance optimization. Every database in Snowflake will always have a public schema that is automatically created upon database creation. Additionally, under every database, you will also find an additional schema called the information schema. The information schema implements the SQL 92 standard information schema and adds additional information specific to Snowflake. The purpose of the information schema is to act as a data dictionary containing metadata that you can query to find information such as all the tables in the system, all columns along with their data types, and more. It is possible to add many additional schemas under a given database, which can help you organize your tables in a meaningful structure.

In this recipe, we did not look at how data could be loaded into a stage. It is possible to load data into a stage from a local filesystem. This method will be discussed in the later chapters. Transient tables are non-permanent tables, but unlike temporary tables, transient tables exist until explicitly dropped and are visible to any user with the appropriate privileges. Transient tables have a lower level of data protection than permanent tables. Data in a transient table may be lost in the event of a system failure. Transient tables should only be used for data that can be recreated in the event that the data is lost. CREATE TRANSIENT TABLE customers_trans AS AS SELECT * FROM customers WHERE TRY_TO_NUMBER(postal_code) IS NULL; A key thing to know about databases and tables used for ETL processing is that the data in those tables will be repeatedly inserted and deleted. If such tables are not specifically configured, you will be unnecessarily incurring costs for the time travel and fail-safe that is stored with every data change that happens for those tables. We will set such databases to be transient (with TRANSIENT) so that the fail-safe option is not the default for the tables in that database. Setting this option does mean that such databases are not protected by fail-safe if a data loss event occurs, but for temporary databases and tables, this should not be an issue. Also, we have set time travel to be zero so that there is no time travel storage as well.Nealon upends the grandeur of the classics, however, by splicing them with images from the farm. "I could never fathom the idea that my mother gave birth to me", Debbie says at one point. "It seems much more likely that I rose up from the slurry pit like some sort of hellish Venus, or that I came out of the arse-end of a cow." Eighteen-year-old Debbie was raised on her family’s rural dairy farm, forty minutes and a world away from Dublin. She lives with her mother, Maeve, a skittish woman who takes to her bed for days on end, claims not to know who Debbie’s father is, and believes her dreams are prophecies. Rounding out their small family is Maeve’s brother Billy, who lives in a caravan behind their house, drinks too much, and likes to impersonate famous dead writers online. Though they may have their quirks, the Whites’ fierce love for one another is never in doubt.

Do note that although we have set the schema to have no time travel and no fail-safe, we can still set individual tables within the schema to be protected by fail-safe and time travel. Setting these options at the schema level sets the default for all tables created inside that schema.They are complicated and intense, but not without good reason. Debbie comes from a house where mental illness is ignored until it winds up bloody and battered at the foot of the stairs – literally. She grew up in a community where "It is socially acceptable to be an alcoholic … as long as you don’t get treatment for it". Debbie is raised on her family's rural dairy farm. She lives with her mother, Maeve, a skittish woman who keeps her past and spends most of her days alone writing and dreaming. Maeve believes her dreams are prophecies. Rounding out their small house is Maeve's brother Billy, who lives in a caravan behind her house and fiercely love and protect Debbie. But Debbie’s life is changing. Earning a place at Trinity College Dublin, she commutes to her classes a few days a week. Outside the sheltered bubble of her childhood for the first time, Debbie finds herself both overwhelmed and disappointed by her fellow students and the pace and anonymity of city life. While the familiarity of the farm offers comfort, Debbie still finds herself pulling away from it. Yet just as she begins to ponder the possibilities the future holds, a resurgence of strange dreams raises her fears that she may share Maeve’s fate. Then a tragic accident upends the family’s equilibrium, and Debbie discovers her next steps may no longer be hers to choose. Snowflake is a note to self to cherish your family and friends - and the moments spend alone with ourselves. Lousie Nealon is an Irish author that you shouldn't miss out on.
