What does influence on time of loading batch data

Hello,
I am newbie at druid, my question is:

What does influence on time of loading batch data (csv file) into druid ?

I mean settings in .json file.

What about granularitySpec ?

Thank in advance,

Tom

Hi Tom, for batch ingestion, in your granularity spec, if the “intervals” field is provided, ingestion should go faster as Druid will not need to run a bunch of extra code to find the intervals of your data.
