How to Improve the Performance of Your Snowpipe Data Load

Organizations that need to load massive volumes of data into Snowflake can do so rapidly, affordably, and with no infrastructure management overhead with the help of Snowflake’s Snowpipe serverless data loading utility. It’s compatible with a wide variety of data stores, such as Amazon S3 and Redshift, and with popular RDBMSs like MySQL and Postgres RDS. This blog post offers best practices for optimizing the performance of Snowpipe data loads using Snowflake Query Accelerator (SPA), which you can read more about here.

What Is Snowpipe? For continuous data loading into cloud-based tables, Snowflake offers a serverless data ingestion utility known as Snowpipe. Snowpipe is optimized and scalable, but sometimes it may experience performance issues if not properly configured. Snowpipe is the way to go if you need to move lots of data quickly or process lots of transactions, or if you just generally need something that can handle high throughput.

FTP and SFTP are not intended for high-volume data transfers. They can be sluggish, undependable, and difficult to manage. FTP and SFTP are both subject to attacks that might result in data loss or damage. Some best practices for optimizing your Snowpipe data load include: Provide the same column names in your CSV files as those on your target table(s). Merge numerous data sets into a single file for each table. Based on the size of your dataset, select the appropriate amount of rows per transaction. Create multiple files when needed. To avoid memory leaks, you should give Snowpipe access to a system with plenty of spare RAM. Make sure you have adequate storage space on your system drive for your Snowpipe dump file.

Snowpipe performance depends on various factors, including CPU speed, operating system, and network quality, among other factors. Even if they are all obtained from identical PCs running identical FTP/SFTP clients, these components might cause significant variances in transfer speeds. This can be due to many factors, including network interruptions between your system and that of CloudPressor or latency built up from having several systems sending files at once, or other unforeseen issues with either your own or our equipment, which we would need to address with specific upgrades for that situation if necessary.

Tuning indexes is an effective strategy for reducing data load. The Snowpipe loader makes use of indexes to speed up the loading process. For example, if an index is needlessly filtering out data, this would result in longer loading times since additional queries must be conducted throughout the load process. There are two main operations that you can use when loading data into a Snowflake table: load and append. Load will insert a new row into the table, whereas append will add rows to an existing table.
