DTU in SQL Azure

•What is DTU (Database Throughput Unit) - DTUs are based on a blended measure of CPU, memory, reads, and writes. As DTUs increase, the power offered by the performance level increases.

•How to monitor it – Portal, T-SQL•How to figure what is based on – T-SQL.

What to do with what we DO NOT have - DBA

•Jobs – From on premise / Automation.•Cross DB Query (Now we have).•Error Log – Query.•DR – Script for Fail Over

18

What to do with what we DO NOT have - Dev

• Retry policy• Short Transactions• Minimized connections

19

Security•TDE•Always Encrypted•RLS•Data Masking•AD•Logins•Audit \ Threat Detection

More•Master DB - queries•Query Store• Index Advisor• In-Memory OLTP•EE – to blob/buffer (Already PP)•2016 Stretch DB into SQL Azure

22

Stories• Huge transaction by developer, He changed tier during the transaction – Need short transactions, every

transaction goes to 3 replicas… sync..

• Changes that are not documented in V2 and V12 (Bulk insert to tempDB due to scratch DB feature) –

Need to be aware.

• Social Feed into shards.

• Archive – DB size limit

• Pricing – developers create objects as they want…

• SAAS data to On-Premise: Mobius – Anonymous Data.

So.. What's Next

•Transactional replication(Already PP)•Security•SQL DWH•Multi DB’s Query (Already PP)
