It consists of virtual warehouses that perform processing tasks on different queries. This layer is where all the hard work is done. This allows for much faster data retrieval during query processing.

Unlike the conventional sort of data storage in rows and columns, Snowflake compresses data and stores it in blocks. Sometimes referred to as the storage layer, Snowflake stores data in Hybrid Columnar Storage. This is comprised as follows: Centralised Database Storage

The key to why Snowflake is better than other data warehouse software lies in its unique 3-layer architecture. The developers originally built it on Amazon Web Services (AWS), but Snowflake app can also run on Microsoft Azure or Google Cloud. What’s more, it is what is known as cloud-agnostic, meaning it can operate across any cloud infrastructure. Unlike other data warehouses, Snowflake’s SaaS solution is natively designed to run on the public cloud. However, there are several reasons why Snowflake is attracting so much attention. Why Snowflake is different?ĭata warehousing is nothing new and choosing the right technology stack for web development is always a case of playing off different options against one another. Next, let’s look at why Snowflake is such a popular choice and how it eclipses the competition. This is the universe in which Snowflake operates. Highly structured data from Excel spreadsheets and so on is simple enough to handle, but warehouses also have to deal with unstructured data ranging from PDFs to photographs to audio files. Operating an effective data warehouse brings a range of challenges, largely depending on the type of data it receives. This will typically be through SQL queries.

The data might come from disparate sources such as CRM systems, OLTP databases and so on, but it is processed and stored in such a way that users can access it to run reports and gather information.

This allows it to be easily accessed and analysed.

But before we get into the nuts and bolts of it, we first need to be clear about what data warehousing is.Ī data warehouse takes all that information that was swilling around in the lake and preserves it in an integrated and organised way. Data warehousingĭata warehousing takes the concept of this data lake to the next level and underpins Snowflake’s SaaS offering. From job files to previous years’ accounts to sundry management reports, everything was in there somewhere if you knew where to search and didn’t mind getting a bit dusty in the process. It was a little like those dusty and disorganised off-site document archives that businesses used to store boxes upon boxes of hard copy data.

When businesses first started using the cloud it was as a repository for data lakes - somewhere to store unsorted data in its native format. Four out of five businesses use multiple public or private cloud apps to fulfil different purposes. The role that the cloud plays in our day-to-day management and use of data has become increasingly significant, but also more varied.

Whether it is required for business reasons, such as transaction details, or for analytics purposes, the majority of data is retained, at least for a certain period of time. The point is most of this data needs to go somewhere. That’s 2.5 raised to the power of 18, or 2.5 billion gigabytes, if that is any easier to conceptualise. According to Osterman Research, the world creates 2.5 quintillion bytes of data every day.
