Important: This feature is in limited release. Before using the low-latency match (LLM) service, contact Tamr Support at [email protected] to discuss your use case and for configuration assistance.

Enabling Authorization

By default, the LLM service endpoints do not authorize users. You can enable authorization for these endpoints. When enabled, authorization for LLM endpoints is consistent with the user permissions and access configured in the Tamr Core UI.

To enable authorization for LLM endpoints:

1. Set the value of the configuration variable TAMR_LOW_LATENCY_AUTH_ENABLED to true. See Creating or Updating a Configuration Variable.
2. Restart Tamr Core and its dependencies. See Restarting Tamr Core.

Tuning Throughput and Latency

You can tune the throughput and latency of the LLM service.

• Throughput is the total time to match a set of records.
• Latency is the total time between request and first response.

Before You Begin:
Parts of the LLM service use port 9170. To use the service, open this port.

To configure throughput and latency for the LLM service:

1. Set the value of the configuration variable TAMR_LLM_BATCH_SIZE to the expected largest batch size using the administration utility. See Creating or Updating a Configuration Variable.
   The default value is 1000.

• A lower value reduces latency while decreasing throughput.
• A higher value increases latency while increasing throughput.

2. Restart Tamr Core and its dependencies. See Restarting Tamr Core.
