timestamp in filename for batch ingestion

I have tones of old files, which have timestamp in filename, but no timestamp inside a file. Is it possible to ingest such data, or I need to do some scripts to add timestamp to the file body?

Hi Dmitry, you can ingest this data and Druid will add a ‘default’ timestamp. There is a hidden value of ‘missingValue’ in the timestamp spec that you can set and Druid will take data without a timestamp. You can set that value to the timestamp of your file.
