The code to combine Apache NiFi with Apache Pulsar is now open supply, Cloudera and StreamNative introduced immediately. The mixing could possibly be a boon for firms seeking to simplify the event of real-time purposes atop streaming knowledge flows, and will present one other competitor to Apache Kafka and Confluent.
Apache NiFi is a software program framework for creating real-time knowledge flows between completely different methods utilizing visible improvement strategies. The software program was initially developed by the NSA, and most of the major engineers for NiFi have labored at Cloudera since 2018, when it acquired Hortonworks (Hortonworks, in flip, purchased Onyara, the first developer of NiFi, again in 2015).
Apache Pulsar, in the meantime, is a distributed messaging and knowledge streaming platform that competes with Apache Kafka and is backed by the industrial outfit StreamNative. The pub/sub system was initially developed at Yahoo, which launched it as open supply in 2016. Since then, it has been adopted by a lot of giant firms, together with Tencent, Verizon Media, Comcast, and Overstock. Splunk additionally opted for Pulsar over Kafka to be the core of it’s the Splunk Information Stream Processor (DSP), which it debuted in 2020.
Ostensibly, NiFi and Pulsar are each real-time streaming knowledge methods, however they occupy completely different ranges of the rising stack. NiFi is extra involved with the sensible elements of automating the motion of huge quantities of knowledge (it was initially known as Niagrafiles, as a play on Niagara Falls). Pulsar supplies the long-term storage of occasion knowledge and exposes interfaces to different frameworks , like Apache Spark and Apache Flink, for the event of analytics and knowledge purposes atop streaming knowledge.
By combining the 2 methods, prospects can get a single place to handle real-time knowledge for short-term and long-term use instances, Cloudera says.
“Apache NiFi and Pulsar’s capabilities complement each other inside fashionable streaming knowledge architectures,” the corporate says in its announcement. “NiFi supplies a dataflow resolution that automates the stream of knowledge between software program methods. As such, it serves as a short-term buffer between knowledge sources slightly than a long-term repository of knowledge.
“Conversely, Pulsar was designed to behave as a long-term repository of occasion knowledge and supplies robust integration with common stream processing frameworks akin to Flink and Spark,” the corporate continues. “By combining these two applied sciences, you’ll be able to create a strong real-time knowledge processing and analytics platform.”
The advantages stack up from each side of the aisle. From the Pulsar viewpoint, the mixing with NiFi brings extra dataflow automation capabilities, together with a big array of connectors in addition to options like prioritization, again stress, and edge intelligence, the corporate says.
NiFi customers, in the meantime, achieve the long-term retention of Pulsar, which may retailer petabytes of knowledge in a dependable method, in addition to the Spark and Flink interfaces for extra refined software improvement.
“In brief, NiFi’s in depth suite of connectors makes it simple to ‘get knowledge in’ to your streaming platform, and Pulsar’s integration with Flink and Spark makes it simple to get real-time insights out,” Cloudera says. “Combining these applied sciences collectively creates an entire edge-to-cloud knowledge streaming platform that can be utilized to supply real-time insights throughout a number of software domains.”
There are numerous use instances that may profit from this integration, together with ingesting and parsing log knowledge for cybersecurity; analyzing giant quantities of IoT and sensor knowledge within the manufacturing or the oil and fuel business; and real-time processing of ticker knowledge to energy algorithmic buying and selling in monetary providers.
The code that integrates the 2 frameworks is being distributed by Cloudera in its Cloudera DataFlow Platform (CDF) providing, which is open supply. Cloudera says the processors shall be obtainable beginning with model 7.2.14 of CDF on the general public cloud. Clients may obtain the processor from the maven central repository in the event that they wish to use them on different NiFi clusters, the corporate says.
