Supported Data Types

Type

Description

char

Character

float

Float type (32-bit float)

double

Double floating point type (64-bit float point)

bool

Boolean type. Available values are 0/1 and true/false.

long

Long integer (value range: -2^63 to 2^63-1)

int

Integer (value range: -2^31 to 2^31-1)

date

Date. Currently, the following formats are supported:

  • YYYY-MM-DD HH:MM:SS
  • YYYY-MM-DD
NOTE:

The value of MM or DD must consist of two digits. If the day or month number contains only one digit, add 0 before it, for example, 05/01.

string

Variable-length string

Data Import Restrictions

For details about how to import data, see .

The restrictions on importing hundred-billion-edge graphs are as follows:

  • Importing Data Concurrently

    Multiple data files can be imported at the same time. To improve the import speed, split a large file into OBS files that each does not exceed 5 GB.

  • Uploading Import Logs to OBS

    Set the logDir parameter to save import logs where you can find the error cause.

  • Importing Edge Data

    If you import only edges of a hundred-billion-edge graph, DLI cannot automatically generate vertices for the graph. If only edges are imported, you cannot query vertices or access the graph from vertices. You are advised to import vertex data too.
