KKcorps opened a new issue, #8726:
URL: https://github.com/apache/pinot/issues/8726
Steps to reproduce -
1. Add schema
```
{
"schemaName": "tSCalibrationRecord",
"dimensionFieldSpecs": [
{
"name": "deviceId",
"dataType": "STRING"
},
{
"name": "nnTransId",
"dataType": "STRING"
},
{
"name": "status",
"dataType": "STRING"
},
{
"name": "header_js",
"dataType": "JSON"
},
{
"name": "refData_js",
"dataType": "JSON"
},
{
"name": "deviceActivity_js",
"dataType": "JSON"
},
{
"name": "geoData_js",
"dataType": "JSON"
},
{
"name": "nmtProcData_js",
"dataType": "JSON"
},
{
"name": "baroContextData_js",
"dataType": "JSON"
},
{
"name": "hvacData_js",
"dataType": "JSON"
},
{
"name": "gnssData_js",
"dataType": "JSON"
}
],
"dateTimeFieldSpecs": [
{
"name": "fixTimestamp",
"dataType": "LONG",
"format": "1:MILLISECONDS:EPOCH",
"granularity": "1:MILLISECONDS"
}
]
}
```
2. Add table
```
{
"REALTIME": {
"tableName": "tSCalibrationRecord_REALTIME",
"tableType": "REALTIME",
"segmentsConfig": {
"schemaName": "tSCalibrationRecord",
"retentionTimeUnit": "DAYS",
"retentionTimeValue": "30",
"replication": "1",
"timeColumnName": "fixTimestamp",
"allowNullTimeValue": false,
"replicasPerPartition": "1",
"completionConfig": {
"completionMode": "DOWNLOAD"
}
},
"tenants": {
"broker": "DefaultTenant",
"server": "DefaultTenant",
"tagOverrideConfig": {}
},
"tableIndexConfig": {
"invertedIndexColumns": [],
"noDictionaryColumns": [],
"streamConfigs": {
"streamType": "kafka",
"stream.kafka.topic.name": "calibrationrecord",
"stream.kafka.broker.list": "localhost:9092",
"stream.kafka.consumer.type": "lowlevel",
"stream.kafka.consumer.prop.auto.offset.reset": "largest",
"stream.kafka.consumer.factory.class.name":
"org.apache.pinot.plugin.stream.kafka20.KafkaConsumerFactory",
"stream.kafka.decoder.class.name":
"org.apache.pinot.plugin.inputformat.json.JSONMessageDecoder",
"realtime.segment.flush.threshold.rows": "0",
"realtime.segment.flush.threshold.time": "24h",
"realtime.segment.flush.threshold.segment.size": "150M"
},
"rangeIndexColumns": [
"fixTimestamp"
],
"rangeIndexVersion": 2,
"autoGeneratedInvertedIndex": true,
"createInvertedIndexDuringSegmentGeneration": false,
"sortedColumn": [
"deviceId"
],
"bloomFilterColumns": [],
"loadMode": "MMAP",
"onHeapDictionaryColumns": [],
"varLengthDictionaryColumns": [],
"enableDefaultStarTree": false,
"enableDynamicStarTreeCreation": false,
"aggregateMetrics": false,
"nullHandlingEnabled": false
},
"metadata": {},
"quota": {},
"routing": {
"instanceSelectorType": "strictReplicaGroup"
},
"query": {},
"ingestionConfig": {
"transformConfigs": [
{
"columnName": "header_js",
"transformFunction": "jsonFormat(header)"
},
{
"columnName": "deviceActivity_js",
"transformFunction": "jsonFormat(deviceActivity)"
},
{
"columnName": "refData_js",
"transformFunction": "jsonFormat(refData)"
},
{
"columnName": "geoData_js",
"transformFunction": "jsonFormat(geoData)"
},
{
"columnName": "nmtProcData_js",
"transformFunction": "jsonFormat(nmtProcData)"
},
{
"columnName": "baroContextData_js",
"transformFunction": "jsonFormat(baroContextData)"
},
{
"columnName": "hvacData_js",
"transformFunction": "jsonFormat(hvacData)"
},
{
"columnName": "gnssData_js",
"transformFunction": "jsonFormat(gnssData)"
}
]
},
"isDimTable": false
}
}
```
3. Push some records in the following format
```
{"header": {"nnTransId": "9003", "rid": 1, "timestamp": 1234567890123)},
"status": "N200", "deviceId": "test-3", "fixTimestamp": 1234567890123),
"deviceActivity": {"acts": [{"aT": "KEEN", "cooor": 0.17487478}, {"aT": "KEEN",
"cooor": 0.3853051}], "charging": True, "revisitId": 1821124849, "elapDay": 23,
"revisitCount": 12}, "refData": {"pressure": 0.76513326, "pV": 0.22455376,
"temperature": 0.32653052, "tV": 0.8554907, "distK": 0.8151323, "avDis":
0.6324501, "stat": 23, "timestamp": 1646730249900}, "geoData": {"metHa":
0.018798769, "flat99": 0.21407795, "ness99": 0.40781218, "builOv": [],
"overDist": {"oPer": 0.49921197, "distribution": [0.9640298]}, "bCut":
0.29687208}, "nmtProcData": {"unTerrPA": 0.44992816, "terrPa": 0.35981137},
"baroContextData": {"davPA": 0.7646854, "bvPA": 0.23593152, "bvPer":
0.21551955}, "hvacData": {"cvPA": 0.6843114, "cbCon": 0.024642766}, "gnssData":
{"dodVal": 0.64749956, "iodVal": 0.33511257}}
```
3. Update schema in pinot to add the following column
```
{
"name": "header_nnTransId",
"dataType": "STRING"
}
```
4. Update table in Pinot to add the following column
```
{
"columnName": "header_nnTransId",
"transformFunction": "JSONPATHSTRING(header_js, '$.nnTransId')"
}
```
5. Publish data again. The column `header_nnTransId` appears `null` when
queried in Pinot when it should contain the correct value.
Optional: Verify after triggering `RealtimeSegmentValidationManager` job
