Getting Data into Vertica

Vertica provides many ways to read data. You can load data into the database from a variety of sources, optionally transforming it in various ways. You can read data in place in its original format using external tables. You can use streaming, and you can import data from other Vertica databases. See Common Use Cases for an introduction.

Most data-loading operations, including external tables, revolve around the COPY statement, which has many options. This book focuses on COPY-based reads (data load and external tables). Other data-loading options supported by Vertica are described elsewhere:
