Tipe primitif

Tabel berikut mencantumkan tipe primitif yang didukung oleh skema Iceberg.

Catatan tentang batasan versi: Tipe yang ditandai sebagai V3—termasuk timestamp_ns, timestamptz_ns, unknown, geometry, dan geography—hanya didukung jika "format-version" Iceberg diatur ke 3. OSS Tables menggunakan V2 secara default. Untuk menggunakan tipe V3, Anda harus menentukan "format-version": "3" dalam properti tabel.
