Dirk, Second granularity is done:
https://github.com/kairosdb/kairosdb/issues/246Just need to document and release this bad boy.
Loic, Query engine changes that are in my head. I think of the query as a directed acyclic graph (DAG). Each component in the graph is a query component that either does a sum or groups by or any other operation that then has a stream of data coming out of. The current engine is kind of a limited version of this, what I want to build is one that is more generic where components can easily be swapped around. So when you create a query you would define the DAG, yes the query language will start out being major ugly, but then I'm thinking that abstractions could be built on top of it. Ideally a sweet UI that lets you drag and drop components to create the DAG.
That is the rough direction I want to go with it. It will be a challenge but I'm pretty sure I can do it.
