TO-DO List› Into Azure

› DB Stretching› SQL Server data files in Azure

› SQL Server Engine › JSON Support› Query Store

› In-Memory Computing› In-Memory OLTP - Memory-Optimized Tables› In-Memory Columnstore Indexes

› Security› Row-level security› Dynamic data masking


Stretch Database


Database Stretching› Why? Transactional data/save money› Not same as Linked Server› Microsoft charges you when query data not

when move itAzureLocal DB


SQL Server data files in Azure› Save mdf /ldf files in Azure Blob storage› Why?

› Backups› High Availability› Security Azure

SQL Server (on premises)

DB 1

DB 2

DB 3

MDF LDF

Azure Blob Storage


JSON support› Native support (like xml)› What to do ?› Export/export data from string to JSON› Format strings (varchar) as JSON› Query› Validate string against JSON standards


Query store› New in 2016 and SQL Azure v12› Bunch of tables:

› sys.query_store_plan , sys.query_store_query , sys.query_store_query_text

› Why?› Find and fix› How many time execute a query› Top n queries› Audit the history of queries


In-memory OLTP› i.e. Memory-optimized tables› ACID? YES !› Data in memory, saved on commits/check

points› Data consistency? Using row versioning› Durable/nondurable data? Both are available› How to access data? T-SQL and Native-

complied table/sp


In-memory ColumnStore indexes


In-memory ColumnStore indexes

ID Name Date Amount

Name

ID Amount

RowStore ColumnStore


In-memory ColumnStore indexes› Columnstore Index (memory-optimized)› What is new? Clustered Index› Massive better performance !


Row-level Security – aka RLS› 2014 – enhancement in 2016› Why? Multi-tenants DB
