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 These features are no longer necessary because they have been superseded already by improved approaches for using the TigerGraph platform.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 and above 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

STRING_SET_COMPRESS

Use SET<STRING COMPRESS>

STRING_LIST_CONPRESS

UINT_SET

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
