Flex Parsers Reference
Vertica supports several parsers to load different types of data into flex tables. The parsers in this section are specific to flex tables. The parsers described in Parsers for Various Data Formats can also load data into flex tables.
All flex parsers store the data as a single Vmap in the
__raw__ column. If a data row is too large to fit in the column, it is rejected. Vertica supports null values for loading data with NULL-specified columns.
For information about how you can use each type of flex parser, see Using Flex Table Parsers.
