Memory Optimization Advisor – SQL Server 2014 CTP2

,

SQLServer 2014 CTP2 came with an inbuilt tool called Memory Optimization Advisor which will help you in migrating your normal tables to memory optimized tables.

Where can I find this tool ?

All you need to do is right click the table you want to migrate, and choose the option Memory Optimization Advisor.

MOA1

The tool will launch with a detailed description of what its capable of

MOA2

I decided to play around with this tool, and here are my observations -

Note - This is still CTP, so things can change during RTM/GA phase.

I started of with a normal table named Employee which has 3 Col and 3 rows data on it. Nothing big, pretty simple.

Launched the advisor, and the initial checks were all green. [Be sure to carefully analyze the checks, they are all interesting.]

MOA4

The wizard also has the ability to export a report (Who doesn’t like a report these days !)

I clicked next to proceed, and the wizard gave me some information about the limitations of memory optimized object, and a link which will explain the limitations in detail.

MOA5

I liked these warnings, because its telling me well in advance about the limitations so that I will be more careful on what I’m up to.(Everything has a cost associated with it !)

Next up is some interesting stuff. The wizard is forcing me to select the options for memory optimized objects. I have the option to mention memory optimized file group,name and the file path.

I also have the option to re-name the original table, copy data from the original table to the memory optimized table and a check box to mention if the table needs to be moved with no data durability.(Default being both schema/data durability).

I decided to go with all defaults as this was a test case.

MOA6

One of the other cool option which the above wizard window gave is this value -

MOA7

I presume that this value will be the cost of size in memory which will be needed when the table is moved as a memory optimized object. I might not be right at this point, but I will update this post in case this is not true.

Next screen in the wizard talks about primary key and index creation. I decided to make column ID as the primary key with a NON-CLUSTERED HASH Index and a bucket count of 1024.

MOA8

The final screen provided me a summary of my selections.

MOA9

Yet another cool feature in the wizard is that it allowed me to script everything before I finalize my selections.

I decided to hit Migrate, and wanted to see how it goes.

Viola,all clean and green !

MOA10

The wizard was smart enough to rename the old table,and created a memory optimized one for me.

MOA12

I had scripted out everything before hitting migrate and that file looked like this -

MOA12_1

Conclusion

This is a very neat feel good to have tool and those warnings and pre-checks will definitely help users to streamline issues well before they are IN MEMORY !

Thanks for reading and keep watching this space for more !
