Configuring Low-Latency Match Service

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.

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
