How many metrics does Druid support?

I’ve went through the tutorial in the website.

Very cool products, especially the pivot UI.

In my case, one piece of our data has two parts:

personal information part, such like: age,sex,location

items with values part: item1,value1; item2,value2;…

The problem is that there are thounds of the items, even one person only have hundreds of items.

I want to treat all the items as the metrics, each item as one column for the store.

So the row will be very wide.

Is it OK in Druid?


Druid should be able to support a wide (large) number of columns, in the thousands. Try to index your data and see how big the resulting segments are.
