I have a csv dataset without timestamp field is it possible to upload that csv file without that field. I have tried doing it but its not working. I added timestamp field to a sample dataset and it worked!. Is timestamp field mandatory for druid datastore?
Yes you need a time column, druid uses such a column as a way to index the data. So a fake time column should be enough to trick druid BUT BUT If your data and query workload do not include time, druid is not your best tool thought!!
