Data bottlenecks are creating
business bottlenecks that’s
impacting growth and innovation!

Currency Oil
Digital transformation is all about the data…
But what if your data is slow and that’s not being
utilized for analytics or in a timely manner?
Data is the new

Today business users think of analytics as a set of boring reports
and dashboards … they don’t want yesterdays data tomorrow!
of enterprise data
in used for analytics….

Performance remains a key Database challenge..

Trends affecting your Database strategy..
Database
› Increasing transaction volume
› Data volume explosion
› Continuous 24x7 availability
› Stronger security measures
› All types of data formats
› New analytical requirements
› Faster access to information
› Co-related/unified data access
› More self-service capabilities
› Unpredictable workloads/patterns
DatabaseDatabase

Businesses want real-time access to information…
› Mobile devices – we need data now!
› Competitive pressure – to act more quickly
› Pressure from businesses (LOB) - to support real-time data access
› New insights, advanced analytics – real-time BI
› Global business – that needs global real-time access
› IOT Applications – sensors, devices . .
› Lower cost of memory and computing

TREND – The need for Fast Data
Real-time
Mostly
Batch
FAST DATA

What is Fast Data?
Fast Data is combining Systems of Engagement (batch) and
Systems of Record(Real-time) together quickly to support
new next-generation business analytics.
Systems of engagement (SOE)
• Mobile, web, and smart devices
• Frequent changes
• Delight clients
• Delivered frequently
Systems of record (SOR)
• Stable requirements
• Highly transactional
• Less change
• Delivered infrequently
Forrester estimates that 20% of all data in an enterprises
is Fast Data, and that’ll double over the next three years.

Data
Traditional DataReal-time data

Key capabilities you need for Fast Data Strategy
› Distributed In-memory computing layer
› Low-latency access to large volumes of data
› Ability to integrate data from disparate data sources
› Continuous availability of the database/data platform
› Support for scale-out architecture to support extreme scale
› Ability to support hybrid environment – on-prem and cloud
› Easy to deploy, highly automated and with built-in intelligence

Apache Spark offers new possibilities…
› Open Source distributed computing framework that uses in-memory
platform to scale, process and provide low-latency access
› Key benefits: i) Performance, ii) Supports streaming and complex
analytics, iii) Supports SQL, iv) Easy to write Apps using Java, Scala or
Python.
› Use cases: i) Sensor data processing, ii) Stream processing, iii)
Interactive analytics and data processing platform, iv) Interactive
algorithms in machine learning, v) IOT analytics, vi) Complex analytics.
› Adoption: Current adoption of Apache Spark is estimated at 30% in
large enterprises likely to double in the next three years.

Road Map for your Fast Data Strategy

Recommendations
› In the era of big data, you need to look beyond traditional data
architectures to succeed and gain competitive advantage.
› Fast data strategy needs to be on your roadmap, focusing on making
data available more quickly to business users and decision makers.
› Look for automation, simplification and easy-of-use database solutions
that can help support faster time-to-value initiatives.
› Look at in-memory and scale-out architectures to support new
business analytics to grow business and innovate.
› Look at open source that can provide lower cost and deliver a platform
to support your fast data strategy.

Who We Are
The open source home and commercial provider
of Redis
Open source. The leading in-memory data
structure store, supporting any high
performance operational or analytic use case.

• Used by developers like “Lego” blocks
• Enables data to be processed on the database level
rather than the application level
• Turns complex functionality into a single command
such as:
"Get the e-mail address of the user with the highest score in a game that
started on July 24th at 11:00pm PST”
ZREVRANGE 07242015_2300 0 0

• Enable solving complex problems by creating relations between
data structures, using standard or custom (Lua) commands
• The result: cleaner, more elegant code, faster execution time

20
Extensibility: Modules Extend Redis Infinitely
• Add-ons using a Redis API for seamlessly adding to
it use cases and data structures
• Modules enjoy Redis’ simplicity, super high
performance, infinite scalability and high availability
• Modules can be created by anyone. Certified by Redis Labs.

Example : Redis For Bid Management
The Application Problem
• Many users bidding on items
• Need to instantly show who’s
leading, in what order and by how
much
• May also need to display analytics
like how many users are bidding in
what range
• Disk-based DBMS-es are too slow for
real-time, high scale calculations
Why Redis Rocks This
• Sorted sets automatically keep list of
users and scores updated and in
order (ZADD)
• ZRANGE, ZREVRANGE will get your
top users
• ZRANK will get any users rank
instantaneously
• ZCOUNT will return a count of users
in a range,
• ZRANGEBYSCORE will return all the
users in a range by their bids

26
Redis Sorted Sets
ZADD item:1 10000 id:2 21000 id: 1
ZADD item:1 34000 id:3 35000 id 4
ZINCRBY item1:1 10000 id:3
ZREVRANGE item:1 0 0
id:3
Item: 1
id:3 44000
id:4 35000
id:1
id:2
21000
10000

27
Example : Redis For Recommendations
The Application Problem
• Users, items, likes, dislikes, similarities
• Set comparisons of user likes, user
dislikes should help create similarity
scores, which can then be stored in a
sorted set
• Set comparisons of similar user
likes/dislikes with items not purchased
by current user should yield suggestions
• High speed and low latency
requirements
Why Redis Rocks This
• Redis Sets are unordered collections
of strings- SADD to add objects to
each tag
• Set operations executed in –
memory, blazing fast speeds
• SINTER, SINTERSTORE to intersect
multiple sets
• SUNIONSTORE to add multiple sets
• SISMEMBER to determine membership,
SMEMBERS to retrieve all values
• Sets and Sorted sets combined are a
great choice for recommendation
engines

Spark & Redis – Serving Layer & Accelerator
Internal accelerator

31
Accelerate Spark Time-Series with Redis
Redis sorted sets accelerate time series data
processing by 100 times compared to other in-
memory K/V stores
Example time series data: Stock prices for 1024
stocks over 32 years

32
Accelerating Spark Time-Series with Redis
Redis is faster by upto 100 times compared to HDFS
and over 45 times compared to Tachyon or Spark
