Oracle Database In-Memory Goals

Until Now Must Choose One Format and Suffer Tradeoffs
Row Format Databases vs. Column Format Databases
Row
 Transactions run faster on row format
– Example: Insert or query a sales order
– Fast processing few rows, many columns
Column
 Analytics run faster on column format
– Example : Report on sales totals by region
– Fast accessing few columns, many rows
SALES
SALES

Oracle In-Memory Columnar Technology
• Pure in-memory column format
• Not persistent, and no logging
• Quick to change data: fast
OLTP
• 2x to 20x compression
• Enabled at table or partition
level
• Available on all hardware
platforms

SALES
Pure In-Memory Columnar

Scans Billions of Rows per Second per CPU Core
• Each CPU core scans local
in-memory columns
• Scans use fast SIMD vector
instructions
• Originally designed for
graphics & science
• Billions of rows/sec scan
rate per CPU core

SQL is Critical
“….the complexity of dealing with a
non-ACID data store in every part of
our business logic would be too
great, and there was simply no way
our business could function without
SQL queries.”
Google, VLDB 2013
“[Facebook] started in the Hadoop
world. We are now bringing in
relational to enhance that. ... [we]
realized that using the wrong
technology for certain kinds of
problems can be difficult.”
Ken Rudin, Facebook, TDWI 2013

Performance Improvements
26

Advanced Index Compression
27
• Compresses indexes to reduce their overall storage requirement
– Less space required on disk
– Better use of the database cache
• Indexes are compressed by between 1 – 3 times
• Little or no discernable overhead
• Compression Advisor extended to describe the possible benefits of this
feature

Attribute Clustering
Ordering of data so that rows are stored near one another based on column values
• Improved query performance and concurrency
– Reduced physical data access trough smart IO
– Significant IO reduction for highly selective operations
• Optimized space utilization
– Less need for indexes
– Improved compression ratios through data clustering
• Full application transparency
– Any application will benefit
28
Benefits :

Zone Maps
Persisted storage index
• Stores minimum and maximum of specified columns
• Analogous to a coarse index structure
– Much more compact than an index
– Zone maps filter out what you don’t need, indexes find what you do need
• Significant performance benefits with complete application transparency
– IO reduction for table scans with predicates on the table itself or even a joined table
using join zone maps (a.k.a. “hierarchical zone map”)
• Benefits are most significant with ordered data
– Used in combination with attribute clustering or data that is naturally ordered
29
X

Approximate Count Distinct
• Not every query requires a completely accurate result
– “How many distinct individuals visited our website last week?”
• New SQL function for approximate results for COUNT DISTINCT aggregates
– APPROX_COUNT_DISTINCT()
• Approximate results can be significantly faster and use less resources than
exact calculations
– 5x to 50x ++ times faster (depending upon number of distinct values and complexity
of SQL)
– Accuracy > 97% (with 95% confidence)
