Core Connector Core connectors are included with all Alation platform tiers (subject to each tier’s connector limits) and are fully supported by Alation.

Sampling and profiling, including dynamic profiling, is supported from connector version 1.0.2.3423, compatible with Alation version 2022.4 or newer.

For details, see Configure Sampling and Profiling for OCF Data Sources.

Important

To use custom query-based sampling and profiling, ensure that the JDBC URI includes the UseNativeQuery=0 property. If you enable dynamic profiling, then users should ensure that their individual connections also include this property. Find more details about building the JDBC URI in Build the JDBC URI.
