Druid ingestion without timestamp in feed

Hi,

I have a feed which is partitioned by timestamp field. something like this:

/projects/agg/daily_summary/ts=201709251000/

but data itself doesn’t have timestamp column. Is there any way to use this “ts” column as timestamp in druid ingestion spec? Any way to statically define this timestamp?

Thanks,

Suresh

I found a way to do this. example spec:
“timestampSpec”: {

        "format": "auto",

        "column": "ts",

        **"missingValue": "2017-09-25"**

}
