Long-running transaction processing may fail in Red Hat build of Keycloak due to the transaction timeout

Issue

In Red Hat build of Keycloak (RHBK), processing that runs for a long time within a single transaction may stop before completion.

This issue can occur when the processing time exceeds the transaction timeout.

Examples include the following:

• User synchronization from a federated user store
• Importing a realm that contains a large number of users
• Other processing that keeps a single transaction open for a long time

In such cases, the transaction timeout may be reached before the processing completes, resulting in the failure of the operation.
