Developer for Apache NiFi specialist

Skills Required for an Apache NiFi Specialist: To set up Apache NiFi for managing and distributing a data feed effectively, the specialist should possess the following skills: Core Technical Skills: 1. Apache NiFi Expertise: Installation and configuration of Apache NiFi. Designing and managing data flow pipelines. Proficiency in NiFi Processors, such as: Data ingestion: GetFile, GetHTTP, GetKafka, etc. Data transformation: ConvertRecord, ReplaceText, etc. Data distribution: PutFile, PutKafka, PostHTTP, etc. Knowledge of NiFi Registry for version control and deployment of flow definitions. 2. Data Integration and Management: Experience with ETL (Extract, Transform, Load) processes. Understanding of data streaming and batch processing. Ability to connect to various data sources (APIs, databases, file systems, cloud storage). 3. System Administration: Proficiency in server setup and management on Linux/Windows. Knowledge of networking and firewalls for secure NiFi access. Experience with SSL/TLS for secure data transmission. 4. Performance Optimization: Load balancing for NiFi nodes in a clustered environment. Tuning NiFi settings for high throughput and low latency. 5. Security: Setting up user authentication (e.g., LDAP, Kerberos, or NiFi user authentication). Implementing role-based access controls (RBAC). Configuring secure connections (HTTPS, secure processors, etc.). Additional Skills (Preferred): Familiarity with cloud platforms (AWS, Azure, GCP) for deploying NiFi. Knowledge of complementary tools like Kafka, Hadoop, or Spark. Proficiency in scripting (e.g., Python, Bash) for automation and data handling. Experience with data serialization formats like JSON, XML, Avro, or Parquet. Steps for Setting Up Apache NiFi for Managing and Distributing Data Feed: Here’s how a specialist would approach the task: 1. Planning and Design: Understand the data sources, volume, and frequency. Identify the destination systems and data distribution requirements. Design the data flow architecture, including: Ingestion process. Transformation logic. Distribution strategy. 2. Setting Up Apache NiFi: Installation: Download and install Apache NiFi on the designated server. Configure NiFi properties (e.g., [login to view URL], [login to view URL]). Securing the Environment: Enable HTTPS and configure SSL certificates. Set up authentication (e.g., user management, integration with LDAP/Kerberos). Configure NiFi to use encrypted repositories if required. Cluster Setup (if needed): Configure NiFi in a clustered mode for high availability and scalability. 3. Creating Data Flows: Ingestion: Use processors like GetFile, GetHTTP, or ConsumeKafka to pull data from sources. Transformation: Use processors like ConvertRecord, RouteOnAttribute, or UpdateAttribute for data enrichment and transformation. Distribution: Use processors like PutFile, PostHTTP, or PutKafka to send data to targets. Error Handling: Implement retry and failure processors (e.g., LogMessage, PutFile for failed records). 4. Testing the Setup: Test the data flows with sample data to ensure they meet requirements. Validate data integrity and monitor performance. 5. Monitoring and Maintenance: Enable NiFi monitoring tools or integrate with external monitoring (e.g., Prometheus, Grafana). Regularly check logs and system performance. Deliverables for a NiFi Setup Project: Installed and configured NiFi instance. Fully functional data flow pipelines for ingestion, transformation, and distribution. Documentation of the setup, including configuration files and flow diagrams.   •    •  Training or handover session for the internal team.
