Bulk Loading from a Local File System Using COPY

This set of topics describes how to use the COPY command to bulk load from a local file system into tables.

As illustrated in the diagram below, loading data from a local file system is performed in two, separate steps:

Step 1:

Upload (i.e. stage) one or more data files to a Snowflake stage (named internal stage or table/user stage) using the PUT command.

Step 2:

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

Regardless of the stage you use, 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.
