Subject How a new index is built in runtime?
Date Thu, 17 Aug 2017 20:26:25 GMT
Alex P., Vladimir,

Having CREATE INDEX command we can define indexes in runtime. However, it’s unclear how
a new index is built.

Let’s imagine I have a field “name” that was in Person’s model for a while and there
are millions of such objects in the cluster. Now I turned the field into the index in runtime.
How Ignite is going to built the index? Do we iterate over the millions of objects with the
field in background or at the time of the CREATE INDEX execution blocking the latter? Or is
there more sophisticated process?
