• BOTH row and column
formats for same table
• Simultaneously active and
transactionally consistent
• Analytics & reporting use new

analytic queries
– Bloom filter enable 10X faster Joins on
in-memory tables
• 12.2 introduces Join Groups
– Specifies columns used to join tables
– Column share compression dictionary
– Joins occur on dictionary values rather
than data
• Enables additional 2-3x speedup

Oracle Sharding
29
Linear Scalability, Fault Isolation, Global Data Distribution, Cloud Enabled
One giant database partitioned into many small
databases (shards)
Customers Americas
Customers
Customers Europe
Customers Asia
• RAC and Data Guard meet needs of over 99% of applications
while preserving application transparency
• Some Global-Scale OLTP applications prefer to shard massive
databases into a farm of smaller databases
– Avoid scalability or availability edge cases of a single large
system image database
– Willing to customize data model and applications to enable
transactions to be automatically routed to the right shard
• Native SQL for sharding tables across up to 1000 Shards
- Routing of SQL based on shard key, and cross shard queries
- Online addition and reorganization of shards
- Linear scalability of data, workload, users with isolation
PublicPerformance Security Developers Management Availability Big Data Analytics

( CustId VARCHAR2(60) NOT NULL,
FirstName VARCHAR2(60),
LastName VARCHAR2(60),
…
PRIMARY KEY(CustId),
)
PARTITION BY CONSISTENT HASH (CustId)
…
• SQL syntax for creating sharded tables
• Not proprietary APIs as with NoSQL
• Creation of a sharded table automatically
partitions data across shards
• Transparent resharding as data grows
• Choice of sharding methods:
• System managed - consistent hash
• User defined - range, list
• Composite - range-hash, list-hash
• Common reference data (e.g. Price List) is
automatically duplicated on all shards
• Supports shard placement in specific
geographies to satisfy government data privacy

Analytic Views
38
• Moves business logic (Aggregations,
Hierarchies, Calculations) back into
database
• Simple SQL for complex analytic queries
– no joins or GROUP-BY clauses necessary
– navigate through hierarchies without re-
defining calculations
• Works on top of existing tables
– no persistent storage
PublicPerformance Security Developers Management Availability Big Data Analytics
Copyright © 2015, Oracle and/or its affiliates. All rights reserved. |
• Delivers significantly faster analysis for
interactive and highly iterative data
exploration
• Approximations for expensive aggregates:
APPROX_COUNT_DISTINCT (12.1)
APPROX_PERCENTILE
APPROX_MEDIAN
– Find the value for a given percentile, e.g. what
is the amount sold that represents the 90%
percentile of all sales
– Accuracy and error rate provided
– 6-13X faster with error typically < 1%
• Approximate functions used without any
application changes
– Queries automatically re-written to use
approximate functions
– approx_for_aggregation = TRUE
39
• Store approximate aggregates in
materialized views with query rewrite
– Not previously possible to use MV’s with
distinct and percentile aggregates
New in 12.2 Approximate Query Processing
Not every query requires a completely accurate result
PublicPerformance Security Developers Management Availability Big Data Analytics
