Flow isolation describes the ability to treat NiFi process groups which typically run Flow isolation CDF is the first cloud service allowing NiFi users to easily isolate data flows fromĮach other and guarantee a set of resources to each one without requiring administrators ReadyFlow, add it to the Catalog and then use it to create a Flow Deployment. ReadyFlow Gallery The ReadyFlow Gallery is where you can find out-of-box flow definitions.

Once DataFlow has been enabled for an environment, you can start deploying flowĭefinitions to it. Kubernetes infrastructure required by CDF and each environment maps to one Kubernetes Supported environment you have registered with CDP. Environments CDF works in the context of CDP environments. For each flow deployment you can open theĭeployment details pane which shows you KPIs you have defined, system metrics as well as Dashboard The Dashboard is the central monitoring component within CDF showing all flowĭeployments across environments at a glance. Representations of those metrics for a NiFi component in Cloudera DataFlow. Such as memory usage, CPU usage, data flow statistics and so on. Apache NiFi has multiple metrics to monitor the different statistics of the system You can also choose to createĪlerts for your KPIs in Cloudera DataFlow. NiFi dataflow and find the metric to monitor it in NiFi. You can use Key Performance Indicators (KPIs) to monitor critical parts of your NiFiĭeployments on the central monitoring dashboard. Provide a real-time view into your dataflow performance. KPIs KPIs (Key Performance Indicators) are a critical monitoring tool introduced in CDF to

Click the Manage Deployment link in the deploymentĭetails pane to get to the Deployment Manager. Deployment manager The Deployment Manager allows you to access the NiFi canvas of your flow deploymentsĪs well as terminate them. Their lifecycle through the Deployment Manager. You can assign KPIs to flow deployments, monitor them in the CDF Dashboard and manage Other and assign resources to deployments as needed. Independently from each other, allowing users to isolate flow deployments from each Shared Kubernetes resources in an environment. For each flow deployment, CDF creates a dedicated, auto-scaling NiFi cluster on the Using the deployment wizard, you supply configuration parameters, auto-scaling settingsĪnd KPI definitions for your flow deployment. Wizard helps you turn a flow definition into a flow deployment which is processing data. Flow deployment When you initiate the flow deployment process from the CDF catalog, the deployment

The catalog isĪlso where users can initiate new deployments from. Catalog The CDF Catalog is where your flow definitions are stored and where you manage theĬDF flow definition lifecycle from import to versioning, and deletion. To run one of your existing NiFi data flows in CDF you have to export it as a flowĭefinition and upload it to the CDF catalog.

Key concepts Flow definition A flow definition represents data flow logic which was developed in Apache NiFiĪnd exported by using the Download Flow Definition action on a NiFi process group Flow deployments can be monitored from a central dashboard with theĪbility to define KPIs to keep track of critical data flow metrics.ĬDF eliminates the operational overhead that is typically associated with runningĪpache NiFi clusters and allows users to fully focus on developing data flows and ensuring Learn about key Cloudera DataFlow concepts.Ĭloudera DataFlow (CDF) is a CDP Public Cloud service that enables self-serveĭeployments of Apache NiFi data flows from a central catalog to auto-scaling KubernetesĬlusters managed by CDP.
