Snowflake offers a scalable Cloud-based platform for businesses and developers that supports advance Data Analytics. In the past few years, Snowflake has progressively risen to prominence as the top cloud-based data warehouse. Although many data stores are accessible, Snowflake is special because of its architectural features and data exchange possibilities.
The fact that Snowflake offers distinct storage and computation alternatives for data is by far its strongest feature. Snowflake is built to ensure users don’t need much effort or engagement to carry out performance- or maintenance-related tasks. In this region, scaling and the minimum and maximum group sizes happen automatically and rapidly.
Different methods to load the data into Snowflake
- Using SQL Commands: You can bulk load data from any delimited plain-text file, such as Comma-delimited CSV files. You can also bulk load semi-structured data from JSON, AVRO, Parquet, or ORC files.
Bulk loading is performed in 2 phases:
- Files staging: You can stage files in Snowflake on what are known as stages on the inside. Every user and table has a stage. Additionally, Snowflake allows for the creation of named stages, such demo stage. Following are some staging options:
To get started, upload your data files somewhere Snowflake can access. Staging your files is what it means to do this.
Then you load your data into your tables from these staged files.
Internal stages allow storing data files conveniently and securely without using any external resources. You can bypass staging and load data directly from external sites if your data files are already staged in a supported cloud storage location, such as GCS or S3. All you need to do is provide the URLs for the locations.
- Loading the data: A virtual Data Warehouse must be functioning to load data into Snowflake. The warehouse extracts each file’s data, adding the rows as columns to the table. The performance of loading might be affected by data warehouse size. You might want to select a larger Data Warehouse while loading several or huge files.
CSV files may represent relational data in a plain-text file and are simpler to import into database systems like Snowflake.
The files will be kept in a named internal stage before loading.
- Using the Snowpipe: Snowpipe can be used to mass upload data to Snowflake, especially from files staged in other locations. Snowpipe uses the COPY command but has extra features that help you automate this procedure.
Using external CPU resources to load data as files are staged continuously, Snowpipe also does away with the necessity for a virtual warehouse. You are only charged for the data that is loaded.
After files are put to a stage and submitted for ingestion, Snowpipe loads data in minutes. Snowflake controls load capacity using the serverless compute paradigm from Snowpipe, guaranteeing enough computing resources to fulfill demand.
3. Using the Web interface
The data loading wizard in the Snowflake Web Interface is the third method for adding data to Snowflake.
You can easily load a small amount of data into Snowflake using the Web UI by selecting the table you wish to load and then clicking the LOAD button. The wizard streamlines loading by merging the staging and data loading processes into a single operation and immediately deleting all staged files after loading.
The wizard is designed to load just a few files with minimal data. Use one of the other choices if you have a lot of data.
4. Using the Hevo Data: Hevo Data is a No-code Data Pipeline solution that enables hassle-free, automatic data movement from more than 100 sources to Snowflake, databases like SQL Server, BI tools, or any other destination you choose. Without needing to write a single line of code, Hevo fully manages and automates not only loading data from your chosen source but also enriching the data and changing it into a suitable form for analysis. Due to its fault-tolerant architecture, data is handled securely, consistently, and without data loss.
Hevo Data handles all your data preparation requirements, allowing you to concentrate on important business operations and gain much-needed insight into increasing lead generation, keeping customers, and growing your company’s profitability. It offers a consistent and dependable way to manage data in real-time and ensures that your target location always has data ready for analysis.
Pioneers in Cloud Consulting & Migration Services
- Reduced infrastructural costs
- Accelerated application deployment
We have discussed the different methods that a user can use to load the data into Snowflake. Users can choose their methods according to their requirements and the data size they are loading. If the volume of data is less, they can go for Web Interface, and if the data is bulkier, then the user can go for Snowpipe. If the user doesn’t want to code, he can opt for the Hevo Data method. If the user is a fan of traditional SQL, he can opt for loading the data using traditional SQL commands.

1. What is Snowflake?
ANS: – Snowflake is a cloud-based data warehousing platform that enables users to store, analyze, and share data across multiple clouds and regions.
2. What are the different methods of loading data into Snowflake?
ANS: – There are several methods of loading data into Snowflake, including SnowSQL, Snowflake web interface, Snowpipe, and bulk loading.
3. What is SnowSQL?
ANS: – SnowSQL is a command-line tool that allows users to interact with Snowflake using SQL commands. It can be used to load data into Snowflake, among other tasks.
4. How do I use SnowSQL to load data into Snowflake?
ANS: – To use SnowSQL to load data into Snowflake, you first need to create a stage, a storage area for your data. You can then use the COPY INTO command to load data from a file in your local environment or from a cloud-based storage location into the stage. Once the data is in the stage, you can use SQL commands to move the data into your Snowflake tables.
