Note: Notice, that I created a varchar(max) column in a table, that was done deliberately, because I wanted to test if LOB columns are supported in vNext. Unfortunatelly, when I tried to create a nonclustered Columnstore index, I got an error:
The statement failed. Column ‘Note’ has a data type that cannot participate in a columnstore index. Omit column ‘Note’.
However, if you create a clustered Columnstore, you will succeed! Though, you will get the following warning in CTP 1.2:
Warning: Using Lob types (NVARCHAR(MAX), VARCHAR(MAX), and VARBINARY(MAX)) with Clustered Columnstore Index is in public preview. Do not use it on production data without backup during public preview period.
I think it is great that we can now have a LOB varchar columns in Columnstore, because it was a blocker for some scenarios, at least I have seen some of those.
There are a few interesting findings here, so check it out.
