Retrieving Metadata Service (MDS) endpoints and credentials

IBM® watsonx.data integrates with multiple entities like Spark, Db2, NPSaaS, and the like. You require watsonx.data MDS credentials and enpoint to establish connection with the entities at the time of integration.

MDS username is by default ibmlhapikey.

Starting with watsonx.data version 2.2.0, authentication using ibmlhapikey and ibmlhtoken as usernames is deprecated. These formats are phased out in 2.3.0 release. To ensure compatibility with upcoming versions, use the new format:ibmlhapikey_<username> and ibmlhtoken_<username>.

Generating API key

As the watsonx.data administrator, you can:
1. Create service IDs
2. Invite users and grant permissions
Permission required for watsonx.data are MetastoreAdmin in Service access and appropriate roles in Platform access.
