Starting February 5, 2026, Data Lake Formation (DLF) supports public network access via the Paimon REST Catalog API. This feature is currently in public preview.
Public network access lets you connect to DLF from outside an Alibaba Cloud Virtual Private Cloud (VPC) — for example, from a local development machine, an on-premises cluster, or a cross-cloud client.

Limitations
-
SLA: No SLA is provided during public preview. Core service functionality remains fully available.
-
Performance: Throughput (QPS) and response latency depend on Internet connectivity. Public network access has lower QPS and higher latency than VPC internal access. This access method is not suitable for large-scale, high-concurrency production workloads.
Billing
This feature is free during the public preview period. Pricing after public preview will be announced separately.
