Agenda
• Apache MiniFi
• Apache NiFi
• Devices
• Demos
• Questions

4. 4 © Hortonworks Inc. 2011–2018. All rights reserved.
What do we want to do?
• MiniFi ingests camera images and
sensor data
• MiniFi executes Apache MXNet at the
edge
• Run Apache MXNet Inception to
recognize objects in image
• Apache NiFi stores images, metadata
and enriched data in Hadoop
• Apache NiFi ingests social data and
REST feeds
• Apache OpenNLP and Apache Tika for
textual data

5. 5 © Hortonworks Inc. 2011–2018. All rights reserved.
Aggregate all data from sensors, drones, logs, geo-location devices, images,
machines and social feeds.
Collect: Bring Together
Mediate point-to-point and bi-directional data flows, delivering data
reliably to Apache HBase, Apache Hive, HDFS, Slack and Email.
Conduct: Mediate the Data Flow
Parse, filter, join, transform, fork, query, sort, dissect; enrich with weather,
location, Apache OpenNLP and Apache MXNet.
Curate: Gain Insights

Apache MiNiFi
• NiFi lives in the data center. Give it an
enterprise server or a cluster of them.
• MiNiFi lives as close to where data is born
and is a guest on that device or system
“Let me get the key parts of NiFi close to where data begins and provide
bidirectional data transfer"

Edge Intelligence with Apache MiNiFi
à Guaranteed delivery
à Data buffering
‒ Backpressure
‒ Pressure release
à Prioritized queuing
à Flow specific QoS
‒ Latency vs. throughput
‒ Loss tolerance
à Data provenance
à Recovery / recording a rolling log
of fine-grained history
à Designed for extension
Different from Apache NiFi
à Design and Deploy
à Warm re-deploys
