How Intervals should be specified in ingestion spec when timestamp has millis


Our ingestion spec for an avro file has below timestamp spec and granularity spec.

“timestampSpec”: {

                  "column": "uct_time_stamp",

                  "format": "millis"


“granularitySpec” : {


    "segmentGranularity" : "hour",

    "queryGranularity" : "non",

    "intervals" : ["2018-04-05T00:00:00.000Z/2018-04-05T14:00:00.000Z"]


Our avro file has “uct_time_stamp”:1522925279.

No segments are getting created with above configuration and data. Can you please help me in resolving this.



typo in none ?
also the epoch 1522925279 looks like its in seconds but the config says millis
