I just have a simple question about caching in Broker nodes. We have enabled caching on broker nodes since our cluster is fairly small.
Does it cache by the intervals?
For example, I have a service where it would hit Druid multiple times with intervals like this
The timestamp would change based on the local time as we use a library to generate timestamp. We just want a day of data so timestamp doesn’t really matter for us.
My question is. Is it better if we do intervals like this. [“2017-11-04/2017-11-05”]? Or it doesn’t really matter and Druid is smart enough to handle any timestamp?
We have memcached as cache for broker.
