You can then load data from S3 as in the following example. If you use session tokens you must set all AWS parameters at the session level. You can set parameters just for the current session using ALTER SESSION, or change them globally using SET_CONFIG_PARAMETER. You might need to set other AWS Parameters to specify a certificate authority. Session tokens are best used for short-lived sessions. If the token expires before your Vertica session ends, you will need to renew it. => ALTER SESSION SET AWSSessionToken = 'FQoDYXdzEKv//////////wEaDMWKxakEkCyuDH0UjyKsAe6/3REgW5VbWtpuYyVvSnEK1jzGPHi/jPOPNT7Kd+ftSnD3qdaQ7j28SUW9YYbD50lcXikz/HPlusPuX9sAJJb7w5oiwdg+ZasIS/+ejFgCzLeNE3kDAzLxKKsunvwuo7EhTTyqmlLkLtIWu9zFykzrR+3Tl76X7EUMOao元1HOYsVEL5d9I9KInF0gE12ZB1yN16MsQVxpSCavOFHQsj/05zbxOQ4o0erY1gU=' => ALTER SESSION SET AWSAuth = 'ASIAJZQNDVS727EHDHOQ:F+xnpkHbst6UPorlLGj/ilJhO5J2n3Yo7Mp4vYvd' "SessionToken": "FQoDYXdzEKv//////////wEaDMWKxakEkCyuDH0UjyKsAe6/3REgW5VbWtpuYyVvSnEK1jzGPHi/jPOPNT7Kd+ftSnD3qdaQ7j28SUW9YYbD50lcXikz/HPlusPuX9sAJJb7w5oiwdg+ZasIS/+ejFgCzLeNE3kDAzLxKKsunvwuo7EhTTyqmlLkLtIWu9zFykzrR+3Tl76X7EUMOao元1HOYsVEL5d9I9KInF0gE12ZB1yN16MsQVxpSCavOFHQsj/05zbxOQ4o0erY1gU=", "SecretAccessKey": "F+xnpkHbst6UPorlLGj/ilJhO5J2n3Yo7Mp4vYvd", Treat NFS mount points as local files in paths: Doing so allows all database nodes to participate in the load for better performance without requiring files to be copied to all nodes. If you are using NFS, then you can create an NFS mount point on each node. When copying from the local file system, the COPY statement expects to find files in the same location on every node that participates in the query. Use a URL of the form 'S3://bucket/path'.
