The default setting of "queryGranularity"

Hi,

According to “Ingestion Spec” section of Druid document (http://druid.io/docs/latest/ingestion/index.html), the default queryGranularity setting is “no”, which is equivalent to millisecond granularity. IMHO as most people only concern about second-level accuracy of website statistics, this setting is not reasonable because it’s nearly 1000 times less efficient than second granularity in regard to storage space occupation for a site with heavy traffic.
Please correct me if I missed anything.

Hi Yukun, the requirements vary from industry to industry. You can just change the configuration to second level granularity and rollup your data at a second level.
