Big Data Definition (4 Vs)
+ Time to action ? – Big Data + Real-Time = Stream Processing
Characteristics of Big Data: Its Volume, Velocity
and Variety in combination

Ever increasing volume and velocity - Internet of Things
(IoT) Wave
Internet of Things (IoT): Enabling
communication between devices,
people & processes to exchange
useful information & knowledge
that create value for humans

What is Data Ingestion?
Acquiring data as it is produced from Data Source(s)
Transforming into a consumable form
Delivering the transformed data to the consuming system(s)
The challenge: Doing this continuously and at scale across a wide variety of
sources and consuming systems
Ingress and Egress are to other terms referring to data movement in and out
of a system

DataFlow Pipeline
Reliable Data Ingestion in Big Data/IoT
• Flow-based ”programming”
• Ingest Data from various sources
• Extract – Transform – Load
• High-Throughput, straight-through
data flows
• Data Lineage
• Batch- or Stream-Processing
• Visual coding with flow editor
• Event Stream Processing (ESP) but
not Complex Event Processing (CEP)

Ingestion with/without Transformation?
Reliable Data Ingestion in Big Data/IoT
Zero Transformation
• No transformation, plain ingest, no
schema validation
• Keep the original format – Text,
CSV, …
• Allows to store data that may have
errors in the schema
Format Transformation
• Prefer name of Format Translation
• Simply change the format
• Change format from Text to Avro
• Does schema validation
Enrichment Transformation
• Add new data to the message
• Do not change existing values
• Convert a value from one system to
another and add it to the message
Value Transformation
• Replaces values in the message
• Convert a value from one system to
another and change the value in-place
• Destroys the raw data!

Challenges

17.
Why is Data Ingestion Difficult?
Physical and Logical
Infrastructure changes
rapidly
Key Challenges:
Infrastructure Automation
Edge Deployment
Infrastructure Drift
Data Structures and
formats evolve and change
unexpectedly
Key Challenges:
Consumption Readiness
Corruption and Loss
Structure Drift
Data semantics change
with evolving applications
Key Challenges
Timely Intervention
System Consistency
Semantic Drift

Implementing Event Hub – Apache
Kafka

21.
How to implement an Event Hub?
Apache Kafka to the rescue
• Distributed publish-subscribe messaging system
• Designed for processing of high-volume, real time
activity stream data (logs, metrics, social media, …)
• Stateless (passive) architecture, offset-based
consumption
• Provides Topics, but does not implement JMS
standard
• Initially developed at LinkedIn, now part of Apache
• Peak Load on single cluster: 2 million messages/sec, 4.7
Gigabits/sec inbound, 15 Gigabits/sec outbound
Kafka Cluster
Consumer Consumer Consumer

Implementing Data Flow

23.
Apache Flume
distributed data collection service
gets flows of data (like logs) from their source
aggregates them to where they have to be
processed
Sources: files, syslog, avro, …
Sinks: HDFS files, HBase, …

24.
Apache Sqoop
Reliable Data Ingestion in Big Data/IoT
• Sqoop exchanges data between an RDBMS and
Hadoop
• It can import all tables, single table, or a portion of a
table into HDFS
• Does this very efficiently via a Map-only MapReduce job
• Result is a directory in HDFS containing comma-
delimited text
• Scoop can also export data from HDFS back to the
database
$ sqoop import --connect jdbc:mysql://localhost/company
--username twheeler --password bigsecret
--warehouse-dir /mydata
--table customers

25.
Oracle GoldenGate
Reliable Data Ingestion in Big Data/IoT
• Provides low-impact change data
capture solution for Oracle and Non-
Oracle RDMBS
• Non-intrusive
• Low-Latency
• Open, modular Architecture
• Supports heterogeneous systems
• Oracle GoldenGate for Big Data
provides Hadoop and Kafka Support

26.
Apache Kafka Connect
• a tool for scalably and reliably streaming
data between Apache Kafka and other
data systems
• is not an ETL framework
• Pre-build connectors available for Data
Source and Data Sinks
• JDBC (Source)
• Oracle GoldenGate (Source)
• MQTT (Source)
• HDFS (Sink)
• Elasticsearch (Sink)
• MongoDB (Sink)
• Cassandra (Source & Sink)

Apache NiFi & MiNiFi
• Originated at NSA as Niagarafiles
• Open sourced December 2014, Apache
TLP July 2015
• Opaque, file-oriented payload
• Distributed system of processors with
centralized control
• Based on flow-based programming
concepts
• Data Provenance
• Web-based user interface
• Apache MiNiFi focuses on the collection of
data at the source of its creation
