![]() ![]() Here we learned to Work with timestamps in NiFi. The output of the above date and time expressions : Note: we have used the "current_time_to_unixtimestamp" above attribute we have created in step 3 to perform date manipulations. To Get the Day Before attribute value, we need to write it as shown below. To create an attribute, click on the '+' to add an attribute or property then it will ask you to give the property name and value.Īs shown above, we have created different timestamps such as the day before, today, tomorrow, and yesterday day using NiFi expression language. Updates the Attributes for a FlowFile using the Attribute Expression Language and/or deletes the attributes based on a regular expression. To work with timestamps, we will create attributes and predefined functions from the NiFi documentation. Then after we are going to work with timestamps. We scheduled this processor to run every 60 sec in the Run Schedule and Execution as the Primary node. Schedule the GenerateFlow file processor as shown below. This processor creates FlowFiles with random data or custom content. Step 1: Configure the GenerateFlow File.Recipe Objective: How to Work with timestamps in NiFi?.Then drag Generate flow file processor from the components Toolbar into the canvas. ![]() Note: This flow is created to understand how to work with timestamps in NiFi. ![]() We will work with timestamps with NiFi expression languages such as the date and time manipulations in this scenario. Install Ubuntu in the virtual machine.A good example is distributed systems which use an eventual consistency approach.īuild a Real-Time Dashboard with Spark, Grafana and Influxdb System requirements : Data operators find that using accurate timestamps from hardware-based clocks can improve performance and efficiency by reducing data conflicts. It provides a web-based User Interface to create, monitor, and control data flows. It is a robust and reliable system to process and distribute data. In most big data scenarios, Apache NiFi is used as open-source software for automating and managing the data flow between systems. example: date1 " 04:35:38" UTC time. but the problem is different systems returns different timestamps based on machine timezone. Recipe Objective: How to Work with timestamps in NiFi? I need to convert date time to UTC timestamp. ![]()
