A Edge Data Streaming deployment consists of EDS Nodes, Apache Zookeeper, Administrator Daemon, and Informatica Administrator. These
components run on multiple host machines in a distributed application environment. You can install multiple components on a host machine.
The following image shows the components of a
consists of the following components:
A EDS Node is a process that contains one or more specialized threads. The threads work together to transfer data from a source to a target. You can create multiple
s on a host machine. Install EDS Nodes on host machines on which you want to run a source service or target service. A EDS Node can contain multiple services and transformations. Services can include source services, target services, or both types of services. EDS uses a data connection to transport data from a source service to a target service.
Apache ZooKeeper is a centralized service that maintains the data flow configuration information of the
s in a deployment. You can deploy Apache ZooKeeper as a standalone instance or, for high availability and reliability, as a cluster called a ZooKeeper ensemble. When you start a
, it fetches data flow configuration information from ZooKeeper.
is a process that manages the deployment and undeployment of data flows and stores information about the data flows in a database. The daemon process also aggregates information about state and statistics from EDS Nodes.
Informatica Administrator for Edge Data Streaming (the
Informatica Administrator is a web application client that an administrator uses to manage the Edge Data Streaming Service and create users and user groups. The Edge Data Streaming Service is a service that you use to create, deploy, and undeploy data flows and to monitor data flow entities.
If you install the Administrator Daemon, the EDS Node, and Apache ZooKeeper on Informatica platform, you can use the Administrator tool and create and configure the Edge Data Streaming Service.
