Installation and Upgrade

To install Talend Data Preparation in cluster mode, you need to make some additions to the <Data_Preparation_Path>/config/ configuration file.

To perform this installation, you need to install and configure as many instances of Talend Data Preparation, and its dependencies, as necessary.

Before you begin

  • Each product, namely Talend Data Preparation and optionally Talend Dictionary Service, requires the use of a Load Balancer.
  • You have configured MongoDB in cluster mode. For more information, see the MongoDB documentation.
  • You have configured Kafka and Zookeeper in cluster mode. For more information, see the Zookeeper documentation and the Kafka documentation.


  1. Install a first Talend Data Preparation instance.

    For more information on the Talend Data Preparation installation procedure, see Installing Talend Data Preparation manually.

  2. In the <Data_Preparation_Path>/config/ file, edit the property to specify the hosts and ports of the several MongoDB instances.

    Use the following syntax:<host1>:<port1>,<host2>:<port2>,…,<hostN>. The hosts and ports for the different URLs must be concatenated, except for the last host, that will inherit the value of the mongodb.port property. For example:,
  3. Edit the service.cache.file.location and properties to specify the location of your Network File System, or shared folder that must be available to all the Talend Data Preparation instances.
