DESCRIPTION
In this presentation, Scott Gnau from Teradata Labs presents: Teradata Intelligent Memory. The introduction of Teradata Intelligent Memory allows our customers to exploit the performance of memory within Teradata Platforms, which extends our leadership position as the best performing data warehouse technology at the most competitive price,” said Scott Gnau, president, Teradata Labs. “Teradata Intelligent Memory technology is built into the data warehouse and customers don’t have to buy a separate appliance. Additionally, Teradata enables its customers to buy and configure the exact amount of in-memory capability needed for critical workloads. It is unnecessary and impractical to keep all data in memory, because all data do not have the same value to justify being placed in expensive memory.”

TERADATA INTELLIGENT MEMORY
Trends• Memory is 3,000 times faster than disk• Memory per node is increasing
> 96GB -> 256GB ->512GB
• Cost of memory is decreasing
Issues• Memory still 80x more expensive than disk• Not all data fits into memory• Not all data worth 80x premium
Teradata Solution• Create a new extended memory space
for most frequently accessed data
Exploiting Technology Trends
Teradata Intelligent MemoryInnovative In-Memory Technology
• New extended memory space • Improves query performance• A smarter approach than in-memory databases• Leverage large memory capacities in new platforms
What We are Announcing May 8, 2013
• Sophisticated algorithms to track usage, measure temperature, and rank data
• Compliments FSG cache
• Dynamically adjusts to new query patterns
New Extended Memory Space
Intelligent Memory
most recently

FSG Cache
Temporarily store data required for current
queries, purges least recently used
• Hottest data in memory/not all the data
• Integrated into Teradata system
• No need for separate appliance
Improves Query Performance
Performance of in-memory databases without their cost
• Automatic
• Transparent
• No DBA effort
• No SQL changes
• Maintain user access to ALL data for analysis
A Smarter Approach than In-Memory Databases
Extend multi-temperature data management to memory
• Memory Capacities Growing Exponentially
• Traditional Cache Reaches Diminishing Returns
• Data is stored compressed and in columns and rows
• Created extended memory space beyond cache
• Use it in a new innovative way
Leverage Large Memory Capacities in New Platforms
