SQL Server 2014: Overview Phil Brammer @PhilBrammer ssistalk.com
Phil Brammer • Over 13 years’ experience in database technologies, data warehousing, ETL, on-call… • Worked with Teradata at PayPal • Operationally manages multi-terabyte instances • Dabbles a bit in SSIS – ssistalk.com • Microsoft MVP, SQL Server – 7th year
Breakthrough Performance & Scale • In-Memory OLTP (Hekaton) • Columnstore Improvements • Query Performance Improvements • Resource Governor for I/O • Buffer Pool Extension • Scale Optimizations for > 8 socket systems
Enhanced High Availability • AlwaysOn Enhancements • Online Database Operations
Hybrid Scenarios • Smart Backup • AlwaysOn Replica in Windows Azure VM • SQL Server with Azure Storage Integration • On-Prem to Azure Migration
Other • Separation of Duties • Extending PowerView • Windows Server Enhancements
BP & S: In-Memory OLTP • Up to 20-30x throughput • Easy to migrate existing applications • Integrated experience • Full ACID support • All in-memory. No buffer pool, B-Trees • No lock manager, latches, or spinlocks
BP & S: Columnstore • New clustered option • Completely read/writeable • New archive option for even more compression
BP & S: Query Performance Improvements • New cardinality estimator • Incremental statistics per partition
BP & S: Resource Governor • Limit I/O to a Resource Pool • Limit CPU usage; percent, affinity • Limit DOP • Limit Memory
BP & S: Buffer Pool Extension • Ability to extend buffer cache to any volume (SSD) • Improve OLTP performance • No risk of data loss (clean pages) • Easy to implement
HA: AlwaysOn Enhancements • Up to 8 readable secondaries • Ability to use readable secondaries during network failures • Cluster Shared Volume support • Easier troubleshooting • Wizard to add replica to Azure
HA: Online Operations • Single partition online index rebuild • Manage lock priority for SWITCH and online index rebuild operations
Hybrid: Smart Backup • Input storage URL (Azure), retention • Automatically backs up databases • Automatically cleans up • Context aware • Minimal storage costs • Zero hardware management • No media decay
Hybrid: Backup to Azure Storage • Near-bottomless storage • Offsite, geo-redundant • No provisioning • No device management • No media decay • Remote accessibility
Hybrid: AlwaysOn Replica in Azure • Wizard to add a replica in Windows Azure VMs • Eliminates DR site needs (hardware, rent, etc…) • Offload read/backup workloads
Hybrid: SQL & Azure Storage Integration • Native support for SQL Server database files stored as Azure blobs • Can move a single database at a time • Save storage costs • Backed by Azure Storage SLAs • Fast disaster recovery using database attach • Control security with on-prem model
Hybrid: Migrations to Azure VMs • New Wizard to migrate databases to Azure VM • Perfect for DBAs new to Azure • No need of specific Azure knowledge • Time to transfer DB is limiting factor
Other: Separation Of Duties • CONNECT ANY DATABASE • IMPERSONATE ANY LOGIN • SELECT ALL USER SECURABLES • Allows for greater role separations – audit vs admin
Other: Power View for Multidimensional Models • Allows native support for DAX in Analysis Services • via BI Semantic Model
Other: Windows Server Enhancements • ReFS Support • Online resize VHDX • Storage Tiering • SMB improvement • Hyper-V replica improvement • Faster live migrations
