Single-Node Deployments

Beginning with version v.2019.013, Tamr does not support deployments where the server on which Tamr is installed also runs other applications. Only Tamr and its dependencies can run on this server. This applies to on premises or cloud deployments, where Tamr is deployed in a bare metal (non-VM) or a virtual machine environment.

Specifications

Tamr can run entirely on a single server.

Included Services and Ports

A single-node deployment provides access to these microservices at the following default ports.

Tamr Microservices

The following services are available at the listed default ports. In addition, they are available via a proxy at the default Tamr port (TCP 9100).

Service	Default Port	Description
Auth	9020	User authentication
Dataset	9150	Dataset management
Dedup	9140	Deduplication service for mastering projects
Job	8180	Job management for data pipelines
Match	9170	Low Latency Match service
Persistence	9080	Database persistence
Preview	9040	Spark runner for preview of mappings and data transformations
Public API	9180	Public APIs for working with Tamr
Recipe	9190	Orchestration service for tracking tasks and their dependencies

Unify	9100	Tamr front-end application

Optional administrative ports can be found at each of the above ports +1. For example, an administrative port for 9020 is found at 9021. They include endpoints for operational information and ensure that a heavy user request load cannot prevent administrative requests from getting through.
