File Signature

The first part of a NATIVE binary file consists of a file signature. The contents of the signature are fixed, and listed in the following table.

Byte Offset

0 1 2 3 4 5 6 7 8 9 10

Hex Value

4E 41 54 49 56 45 0A FF 0D 0A 00

Text Literals

N A T I V E E'\n' E'\317' E'\r' E'\n' E'\000'

The signature ensures that the file has neither been corrupted by a non-8-bit file transfer, nor stripped of carriage returns, linefeeds, or null values. If the signature is intact, Vertica determines that the file has not been corrupted.
