I have a virtual dataset with the following four columns which is the result of a convoluted MySQL query. The columns are:
user (varchar 65536), dt (date), type (varchar 65536), amount (bigint).
I have created a raw reflection on the dataset that just displays the four columns (and I waited the prescribed 30 seconds after reflection creation) but when I run a simple SELECT * on the dataset the reflection is not used and instead the very complicated MySQL query is executed again. Probably worth mentioning that I updated the whole Dremio install to 1.1.0 earlier on today but I had similar problems with 1.0.8 also.
