What I've Seen
Is it the 1980s or Today?
Common Themes
• A LOT of data
• Slow hardware
• Difficult/limited tools
• Unhappy users
And Yet
• Users want even more data
• Hardware has its limits
• Too many tools
• Upgrades/conversions/legacy
• Cost/time/training
• DBA’s render the data useless
• True analytics = detail + history
• Users are still unhappy
Reaction
• Newest shiny BI/reporting tool
• More/bigger/faster hardware
• Team of DBA's
indexing/aggregating/limit
history

• Easy to Get Started
• Low Cost of Entry
• Secure
• Intuitive
• Autonomy/Control
Snowflake – The Good
• Consolidated Data
• Flexibility
• Less Management
• Reduced DBA
• Transparent

The Promise
• Lots of detail, no more aggregations
• Lots of history, no more
limitations
• Use your tool of choice
• Finally – True Analytics
• No Impact on Production
• Happy Users
Snowflake – The Bad
The Reality
• The more data you have,
• The greater its complexity,
• The higher your concurrency:
• The greater the impact on performance
• Requiring additional compute
• DBA's to aggregate
• Higher monthly cost
Especially for Enterprise Accounts
At best, poor/mediocre results

Snowflake – The Ugly
Your Snowflake Monthly Statement
• Pay-per-Use Model
• GREAT – Just pay for what I use!!
• You pay for:
• Storage, Compute, Users
• B.Y.O.C. – Not an option, because there is too much profit
• Up-Lift: Standard, Premier, Enterprise, Premium, Business Critical
Do they care if your queries take longer?
Do they have a financial incentive to speed up your queries?
Especially for Enterprise Accounts

Top-3 Most Common Issues with Snowflake
Have we gone full circle, AGAIN?
#3. NOT Purpose-Built for Big Data / Performance
• Require M/B/Trillions of Rows of Detail
• High-Concurrency
• Complex Requests
• Unhappy Users

• Unhappy Users
#2. Limited Remedies
• More Compute
• Limit Data
• DBA's Indexing/Aggregating

• Unhappy Users
• More Compute
• Limit Data
• DBA's Indexing/Aggregating
#1. Your Snowflake Monthly Statement
• Out-of-Control Costs
• Mediocre Results
• Unhappy CFO

Dilemma . . .
Requirements & Challenges
• Teradata
• Many Petabytes of Detail Data
• Complex Queries
• Many Users/High Concurrency
• Using a Variety of BI/Reporting/Analysis Tools
• High Performance at Any Scale

Requirements & Challenges
• Teradata
• Many Petabytes of Detail Data
• Complex Queries
• Many Users/High Concurrency
• Using a Variety of BI/Reporting/Analysis Tools
• High Performance at Any Scale
Solution . . .
Plan A:
• What was commercially available?
• Netezza, Greenplum, Vertica,
Postgres, others
• None could scale
• None could perform
• All were too complex to
implement and maintain
Plan B:
• Build

Solution
• OLAP / Pre-Compute
• Ultra-High Performance
• High Concurrency
• No Performance Degradation
• Reduced Complexity
• Easily Handles Complex Queries
• Slice/Dice/Pivot
• Supports BI Tools - SQL
• Unlimited Scale
• Data/Storage
• Compute
• Users/Concurrency
• Low Management
• Easy Implementation
• Cost-Effective

History

Under the Hood: Smart Cuboids
• Each model consists of N-dimension cuboids, which is a combination of several
dimensions in different permutations and combinations.
• Apache Spark is used to build the cuboids, making query results extremely fast.
• When the user sends a query, the model intelligently looks for the
cuboid/segment and quickly returns the results.

TPCH Benchmark
SF=50
Query Response Time | 0.5 Billion
SF=500
Query Response Time | 5 Billion
• No warmup
• Lower is better
• Run each query 3 times
• Record the average time
For Each Dataset:

Hierarchies/KPIs/Calculated Measures/Alias
Excel Tableau PowerBI

Elastic Scaling — Handle Peak Time Automatically
• Fewer compute and storage
resources utilized
• Dynamic on-demand cluster resizing
• Uses spot instances
• Efficient planning for data growth

TCO Benchmark
• Build once, query anytime
• More queries, cheaper
• Will not increase sharply when
dealing with high concurrency

#3. NOT Purpose-Built for Big Data Performance Purpose-Built for Big Data & Performance
• BIG Data (billions/trillions of rows of detail)
• High Concurrency
• Ultra-High Performance (sub-second response)
• Complex Requests (Hierarchies, High
Cardinality, COUNT_DISTINCT)
• Flat/Consistent Performance

#2. Limited Remedies UNLIMITED Scale
• Unlimited Data/Users/Compute
• Little/No Maintenance
