Hello everybody. In this chapter, we are going to study the different ways to COPY data into Snowflake tables, either using bulk load or continuous load with Snowpipe:

  1. Data Loading
  2. Bulk load using COPY INTO
  3. Continuous load using Snowpipe
  4. Typical Exam Questions

Remember that all the chapters from the course can be found in the following link.

DATA LOADING

When we load the data into Snowflake, we usually perform the following steps:

  • Source system → Snowflake Stage → Snowflake Table.

A source system (it can be, for example, your application, or not even that, it can be whatever machine that generates data, like sensors) will generate data that it will send to a stage, for example, AWS S3. Once the data is at any stage, we’ll copy it into Snowflake tables. There are two different ways to do it, Bulk Load or Continuous Load; let’s study the differences.
