About Configuring a Data Load from S3
When you create an S3 Data Load using MC, you have the option of further configuring the load operation. You can optionally specify the following:
Add COPY Parameters
MC performs the load operation with COPY. You can use the COPY Parameters field to further configure the COPY operation. This field accepts parameters that are specified after the COPY statement's FROM clause. For details on these parameters and special requirements, see COPY Parameters.
The FILTER and PARSER parameters must appear in that order and precede all other parameters.
For example, you can specify the DELIMITER and SKIP parameters to separate columns with a comma, and skip one record of input data, respectively:
DELIMITER ',' SKIP 1
You can also add comments in this field with standard C comment notation.
This field does not support SQL comment notation (double hyphen ‑‑).
Capture Rejected Data in a Table
Set Capture rejected data in a table to Yes to create a table that contains rejected row data. You can view this data in the Load History tab.
This table uses the following naming convention:
schema.s3_load_rejections_target-table-name
You must have CREATE privilege on the schema if the table doesn't already exist. When you invoke multiple load processes for the same target table, MC appends all rejections data to the same table. For details, see Saving Rejected Data To a Table.
Set a Rejected Records Maximum
Set Reject Max to the maximum number of rows that can be rejected before the load operation fails. If COPY rejects the specified maximum rows, Vertica rolls back the entire load operation.
