[NOTE]
====
TigerGraph optimizes storage for certain data types internally. Integer-based types such as `INT`, `UINT`, and `DATETIME` may use compressed storage depending on the value. These optimizations are implementation details and may vary by version.

[NOTE]
====
The legacy data type `STRING COMPRESS` has been deprecated since TigerGraph Server 3.0.
