Vertica Caching Limitations

Because of Vertica length limits, mapping of any data type (BINARY, CHAR, VARCHAR, BLOB, and so on) to Vertica cache with length greater than 65000 results in an error, regardless of the data source.

Similarly, Vertica only supports precision up to 15 digits. Any data that you have past 16 digits will get rounded by Vertica. This precision limitation is particularly noticeable when working with REAL, FLOAT, and DOUBLE data types.
