This webinar is for IT professionals who have devoted considerable time and effort growing their careers in and around the Netezza platform. We’ll explore the architectural similarities and technical specifics of what makes the open source Greenplum Database a logical next step for those IT professionals wishing to leverage their MPP experience with a PostgreSQL-based database. As the Netezza DBMS faces a significant end-of-support milestone, leveraging an open source, infrastructure-agnostic replacement that has a similar architecture will help avoid a costly migration to either a different architecture or another proprietary alternative.

2. The Netezza Professional
You

3. ● The skills you have invested in with
Netezza are directly portable to the
Greenplum database. There are
numerous reasons for this, as we will
explore each one.
○ MPP Scalable Performance
(predictable linear scale)
■ Architecture/Data distribution
○ PostgreSQL Based
■ DDL
■ DML
■ Security
1 Skill Set Portability

4. ● Your Netezza knowledge and skills will be
of great benefit when applied to migrating a
Netezza environment to Greenplum. This
will accelerate your tasks through great
efficiency and a demonstrated proficiency.
○ Because of skill set portability,
migration is much more intuitive
■ Similar DDL/DML rooted in
Postgres
○ Export/Import and/or ETL-based
transfer
○ Similar administration interfaces (e.g.
pgAdmin)

5. Enterprise Landscape
Your Company

6. ● The initial attraction to Netezza is not lost with Greenplum. These foundational pillars
that you have become accustomed to will continue to serve you in a Greenplum
environment.
○ MPP ‘divide and conquer’, with knobs if desired/needed (Performance)
○ Open-source based product on commodity hardware (Cost)
○ Don’t need to use all of the knobs (Simplicity)
■ Cost-based optimizer (GPORCA)
3 Continued Benefits of Performance, Cost & Simplicity

7. ● A glaring challenge with the Netezza appliance was its difficulty in handling mixed
workloads. Greenplum’s answer and approach to this common challenge will be both
refreshing and reassuring to you as it proves to be the most common problem facing a
legacy Netezza environment.
○ Optimization built for mixed workloads (Analytics + Operational)
■ Higher-speed short queries
■ Row level locks for updates and deletes on the heap table, for highly
concurrent updates/deletes on the same table
4 Mixed Query Workloads

8. ● As environments have become more diverse in their data sources, the ability to easily
connect these sources to the database engine has been challenging. Greenplum has
simplified these steps, knowing this is an obstacle you face.
○ Integrates with in-memory data grid and object store to post process structured
and unstructured data
○ External tables allow for incredible flexibility
○ JSON format and natural language text with Apache Solr

9. ● Moving from a batch-oriented ingest to a Real-Time ingest can prove challenging. This
is especially true if the underlying technology is not architected with this in mind.
Greenplum’s features for accommodating this transition will make your job easier, with
far less improvising required.
○ Loading speeds scale with each additional node - loads greater than 10
terabytes per hour, per rack.
○ Micro batches
○ Message queues (Apache Kafka integration)

10. ● A typical Netezza environment was designed around an on-premises installation of the
appliance. While Greenplum offers on-prem configurations, it offers many other options that
may make sense for the customer you serve.
○ Runs on leading public clouds: Amazon Web Services (AWS), Microsoft Azure, Google
Cloud Platform (GCP) with Bring Your Own License (BYOL) and Hourly offerings
○ Runs on private clouds: VMware vSphere and OpenStack
○ Runs on-premises (with dedicated hardware): Greenplum Building Blocks (Dell
reference architecture for Greenplum)
