Known Limitations

INTERVAL Data Types

Yellowfin 8.0.0 does not support the INTERVAL data types in Vertica. To load INTERVAL data, set the column format in Yellowfin to Raw Formatter.

BINARY Data Types

Null values of type BINARY, VARBINARY, and LONGVARBINARY in Vertica are successfully loaded into Yellowfin. However, non-null values of these types are not loaded.

UUID Data Type

Yellowfin 8.0.0 does not support the UUID data type in Vertica. To load UUID data, set the column format in Yellowfin to Raw Formatter

Time, Timestamp, TimestampTz and TimeTz Data Types

Seconds are truncated in Typical and Low values of Time, Timestamp, TimeTz, TimestampTz data types. To display these data types with the seconds and milliseconds, set the Time Format of the column to H:mm:ss:S in Yellowfin.

Decimal Data Type

Some Max, Min and [1234.567890] values of Decimal data type are rounded off to two decimal places. To display the complete Decimal values, set the column format to Raw Formatter or Reference Code in Yellowfin.

FLOAT Data Types

By default, the value is either not displayed or is rounded to 2 digits after the decimal point. Workaround is to set the column format to Raw Formatter or Reference Code in Yellowfin.

For information about the Vertica FLOAT data type, see Double Precision (FLOAT) in the Vertica documentation.
