Nifi Concurrent Tasks Limit. NiFi has a web-based user interface for design, control, feedback,
NiFi has a web-based user interface for design, control, feedback, and monitoring of dataflows. This controls the maximum number of threads, from the Thread Pools configured above, that the processor is allowed to use at any one time. Apache NiFi is an easy to use, powerful, and reliable system to process and distribute data Dec 16, 2025 · NiFi Cluster Coordinator: A NiFi Cluster Coordinator is the node in a NiFi cluster that is responsible for carrying out tasks to manage which nodes are allowed in the cluster and providing the most up-to-date flow to newly joining nodes. When you adjust this value, monitor your cpu usage and adjust accordingly. . It is a single-threaded runtime engine, in which data is not persisted across restarts. The project management committee may consider critical bug fixes for essential framework features on an exceptional basis. It controls the maximum number of threads NiFi can request from the server for fulfilling concurrent task requests from NiFi processor components. Aug 23, 2017 · The question says it all. Oct 21, 2024 · For information on how to configure the instance of NiFi (for example, to configure security, data storage configuration, or the port that NiFi is running on), see the Admin Guide. Jul 9, 2023 · The Max Concurrent Tasks property for a port determines the number of concurrent tasks that can be executed on the port. The README document for NiFi Stateless provides far more context as to Mar 3, 2020 · (This is a soft limit, there are some scenarios where a thread can be obtained even when active threads executing has reached this configured max count). The UI can be broken down into several segments, each responsible for different functionality of the application. Apache NiFi is an easy to use, powerful, and reliable system to process and distribute data Oct 21, 2024 · What is Apache NiFi? Put simply, NiFi was built to automate the flow of data between systems. Stateless NiFi provides a different Runtime Engine than traditional NiFi. When configuring a processor, the Scheduling tab provides a configuration option named Concurrent Tasks. Concurrent tasks Learn how and when to configure concurrent tasks. Dec 16, 2025 · NiFi Cluster Coordinator: A NiFi Cluster Coordinator is the node in a NiFi cluster that is responsible for carrying out tasks to manage which nodes are allowed in the cluster and providing the most up-to-date flow to newly joining nodes. It depends on a variety of factors: memory, CPU, the application’s consumption, and many … Oct 21, 2024 · Introduction Apache NiFi is a dataflow system based on the concepts of flow-based programming. It assumes the reader has read enough of the other documentation to know the basics of NiFi. Along with setting "concurrent tasks" on individual processors, there are global maximum timer and event driven thread settings in NiFi (Defaults are 10 and 5 respectively). The "Max Timer Driven Thread Count" is configured under the NiFi Global Menu --> Controller Settings --> General (tab). How can I do one of the following things: How can I limit the number of concurrent tasks running for one processor cluster-wide? Is there any unique and short ID for the N Apr 23, 2020 · Optimizing NiFi with Concurrent Tasks Optimizing any application can be found out to be a tough mission. Oct 21, 2024 · This setup, in terms of transactional units of work, allows NiFi to be very resilient in the face of adversity, ensuring that even if NiFi is suddenly killed, it can pick back up without any loss of data. Oct 21, 2024 · NiFi User Interface The NiFi UI provides mechanisms for creating automated dataflows, as well as visualizing, editing, monitoring, and administering those dataflows. Oct 29, 2019 · Its default values are 10 and 5 respectively. This then limits the number of available threads from the pool that are trying to work through the remaining tasks in the queue. Discover best practices, monitoring tips, and real-world solutions. Overview Apache NiFi is a dataflow system based on the concepts of flow-based programming. While the term 'dataflow' is used in a variety of contexts, we use it here to mean the automated and managed flow of information between systems. Additionally, the data that is sourced can be processed through the entire chain of processors in the dataflow before it is ever even acknowledged from the source. Jan 4, 2017 · Assigning to many concurrent tasks to a single processor will hinder other processors who are looking for cpu time. It supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. Dec 17, 2025 · Apache NiFi 1. An easy to use, powerful, and reliable system to process and distribute data NiFi automates cybersecurity, observability, event streams, and generative AI data pipelines and distribution for thousands of companies worldwide across every industry. Dec 17, 2025 · Apache NiFi is an easy to use, powerful, and reliable system to process and distribute data Oct 21, 2024 · NiFi User Interface The NiFi UI provides mechanisms for creating automated dataflows, as well as visualizing, editing, monitoring, and administering those dataflows.
