I am evaluating Druid for our time series analysis. A little brief about the data set.
We receive check data from restaurants in the real time (Kafka/Storm). All the analysis circles around check time (mostly daily with some hourly). 99% of queries requires time series analysis for one restaurant location.
As I was reading through Druid documentation, I see segments are created on the time windows (daily, hourly, etc). I was read about sharding along the dimensions on top of time slice but could not find enough documentation about that.
Can somebody point me to some documentation that explains how this can be possible or some leads?
