Loading Data from Amazon S3 Using COPY

This set of topics describes how to use the COPY command to load data from an Amazon S3 bucket into tables.

Data loading overview

As illustrated in the diagram above, loading data from an S3 bucket is performed in two, separate steps:

  1. Upload (i.e. stage) one or more data files into an S3 bucket using the upload interfaces/utilities provided by Amazon.

  2. Use the COPY INTO table command to load the contents of the staged file(s) into a Snowflake database table.

    This step requires a running virtual warehouse that is also the current (i.e. in use) warehouse for the session. The warehouse provides the compute resources to perform the actual insertion of rows into the table.

Note

The instructions in this set of topics presume you have read Preparing to Load Data and have created a named file format, if desired.
