V3.0 Removal of Previously Deprecated Features
TigerGraph 2.x contained some features which were labeled as deprecated. These features are no longer necessary because they have been superseded already by improved approaches for using the TigerGraph platform. The new approaches were developed because they use more consistent grammar, are more extensible, or offer higher performance. Therefore, TigerGraph 3.0 has streamlined the product by removing support for some of these deprecated features, listed below:
Data Types
| Deprecated Type | Alternate Approach |
|---|---|
REAL |
Use FLOAT or DOUBLE |
INT_SET |
Use SET<INT> |
INT_LIST |
Use LIST<INT> |
STRING_SET_COMPRESS |
Use SET<STRING COMPRESS> |
STRING_LIST_CONPRESS |
Use LIST<STRING COMPRESS> |
UINT_SET |
Use SET<INT> |
UINT32_UINT32_KV_LIST |
Use MAP<UINT, UINT> |
INT32_INT32_KV_LIST |
Use MAP<INT, INT> |
UINT32_UDT_KV_LIST |
Use MAP<UINT, UDT_type>, where UDT_type is a user-defined tuple type |
INT32_UDT_KV_LIST |
Use MAP<INT, UDT_type>, where UDT_type is a user-defined tuple type |
