1. Azure Table Storage Cheap, fast and scalable storage Anton Boyko Ukrainian Azure Community Founder Microsoft Azure MVP boyko.ant@live.com

2. Say Thank you to Volunteers:  They spend their FREE time to give you this event.  Because they are love our COMMUNITY.  Because they want YOU to learn from the BEST IN THE WORLD.  If you see one of these guys in the hall – buy them a beer/wine, they deserve it.

10. AZURE STORAGE

11. Azure Storage Storage in the cloud  Scalable, durable, available  Exposed via RESTful web services  Only pay for what the service uses

12. Azure Locations

13. Azure Storage Abstractions BlobsDrivesFiles QueuesTables

14. Azure Storage Redundancy Locally redundant Makes multiple synchronous copies of your data within a single datacenter Geographically redundant Same as LRS, plus multiple asynchronous copies to a second datacenter hundreds of miles away Read-access geographically redundant Same as GRS, plus read access to the secondary datacenter

15. Azure Storage Libraries

16. AZURE TABLE STORAGE

17. What is Azure Table Storage? Is not  Relational Database Management System  No-SQL Database Management System  Database Management System Is  Key value storage  Software as a service

19. Azure Table Storage Operations Tables  Create  Query  Delete Entities  Insert  Update  Merge  Replace  Upsert  Delete  Query

20. Azure Table Storage Entity  RowKey  PartitionKey  Binary strings  Indexed fields  Timestamp  Optimistic concurrency  Custom fields  String, Binary, Integer, Double, Guid, DateTime, Bool  There are no fixed schema  Up-to 1MB entity data  Up-to 255 fields (including RowKey, PartitionKey, Timestamp)

21. No Fixed Schema FIRSTLASTBIRTHDATE WadeWegner2/2/1981 NathanTotten3/15/1965 NickHarrisMay 1, 1976 FAV SPORT Canoeing

22. Querying FIRSTLASTBIRTHDATE WadeWegner2/2/1981 NathanTotten3/15/1965 NickHarrisMay 1, 1976 ?$filter=Last eq ‘Wegner’

23. Querying GET /myaccount/Customers() ?$filter=(Rating ge 3) and (Rating le 6) &$top=10 &$select=PartitionKey,RowKey,Address,CustomerSince

24. Purpose of the PartitionKey  Entity location Entities in the same partition will be stored together Efficient querying and cache locality Endeavour to include partition key in all queries  Entity group transaction Atomic multiple Insert/Update/Delete in same partition in a single transaction  Table scalability Target throughput – 500 tps/partition, 20 000 tps/account Microsoft Azure monitors the usage patterns of partitions Automatically load balance partitions Each partition can be served by a different storage node Scale to meet the traffic needs of your table

26. AZURE STORAGE SECURITY

27. Azure Storage Security  HTTPS  Two 512bit symmetric keys per storage account  More granular security via Shared Access Signatures  Ad-hoc  Policy based

28. Azure Table Storage SAS  Table granularity Can grant access to an entire table (tn) or to a table range defined by a table (tn) along with a partition key range (startpk/endpk) and row key range (startrk/endrk)  Access permissions Can grant access rights to the specified table or table range such as Query (r), Add (a), Update (u), Delete (d) or a combination of them  Time range Can limit the SAS token access time. Start time (st) is optional but Expiry time (se) is mandatory, and no limits are enforced on these parameters. Therefore a SAS token may be valid for a very large time period

29. SAS Example GET https://myaccount.table.core.windows.net/MyTable() ?$filter=PartitionKey eq 'Coho Winery‘ &sv=2012-02-12 &tn=MyTable &st=2012-02-09T08:49Z &se=2012-02-10T08:49Z &sp=r &spk=Coho Winery &srk=Auburn &epk=Coho Winery &erk=Seattle &sig=jDrr6cna7JPwIaxWfdH0tT5v9dc=
