Performance
• In-Memory Column Store
• Software in Silicon
• Engineered Systems
Today Oracle Database 18c
• Low Latency Memory Transactions
• 2x throughput for streaming ingest
• 4x throughput for low latency key lookups
• Non Volatile Memory Support
• Multi Tiered Database Cache
• In-Memory Column Store Improvements
• Performance improvements
• Automatic Population

• Ultra-Fast key-based lookup:
– Uses new lock-free In-memory hash index
– Just declare table MEMOPTIMIZE FOR
READ
• New low latency client protocol with
direct access to data engine
• Performance benefits:
– Up to 4x throughput increase for Primary
Key based lookups
– 50% lower response times
Memory Optimized Access for OLTP Workloads

• New streaming ingest:
– Declare table MEMOPTIMIZE FOR WRITE
– Clients performs low-latency write into
in-memory buffer
– Buffered writes drained in background
– Very high throughput inserts since server
issues deferred writes in large batches
• Performance:
– 2x faster throughput than conventional
• 21M inserts per second on 2-socket server
Memory Optimized Access for IoT Workloads

Multitenant
• Container managed database virtualization
• Manage Many as one
• Patching, Backup, Security, Online Cloning, Online
Relocation
• Software as Service
• Shared metadata, Data location transparency
• Per-PDB Switchover
• Transportable Backups
• Snapshot Carousel
• Faster Upgrades

Availability
• Comprehensive HA and disaster recovery
functionality
• Real Application Clusters, Active Data Guard, Recovery
Appliance
• Oracle Golden Gate for heterogeneous
replication
• Scale out and fault isolation with Oracle Database
Sharding
• Zero Impact Grid Infrastructure Patching
• Sharded RAC
• Logically partition data across instances in RAC
• Sharded access for shard-aware applications and
transparency for non-sharded applications
• Sharding improvements
• User Defined Sharding
• Improved Cross Shard Query support

Sharded RAC
• Affinitizes shards to RAC instances
– Requests that specify sharding key will be routed to
the RAC instance that logically holds the shard
– Affinity gives better cache utilization and reduced
block pings across instances
• Requests that don’t specify sharding key still
work transparently
• Gives Sharded Database performance with
minimal application changes
– Just add sharding key to the most performance
intensive operations
Higher performance for shard-aware RAC applications

Security
• Security In-Depth
• Access Controls, Encryption, Redaction, Masking, Auditing,
SQL Firewalls
• Key Vault
• Audit Vault Database Firewall
• Security Assessment Tool

Active Directory
• Integration with Active Directory
• Authorization to database through Active Directory
user/group mappings to database schema users and
roles
• Per PDB Key storage
• Password-less schema creation
• No default passwords

Data Warehousing and Big Data
• The most advanced analytics engine available
today
• Partitioning, Compression, SQL, Analytical Views, Analytical
SQL, Data Mining
• Easily analyze data held in Hadoop with Big Data
SQL
• Big Data Appliance
• In-Memory for external tables
• Automatic propagation of nologged data to
standby
• More Machine Learning algorithms
• Polymorphic Table Functions
• Alter Table Merge Partition Online
• Approximate Query Improvements

Polymorphic Tables: Self-Describing, Fully Dynamic SQL
• Part of ANSI 2016
• Encapsulate sophisticated algorithms
– Hides implementation of algorithms
– Leverage powerful, dynamic capabilities of SQL
– Pass in any table-columns for processing
– Returns SQL rowset (table, JSON, XML doc etc)
• E.g. return credit score and associated risk levelCREDIT RISK
