pinot可以支持多值存儲，默認值存儲
多值主要是配置schema，要在相關的字段中設置 "singleValueField": false
默認值爲在schema中相關字段設置"defaultNullValue": 99
{
"dimensionFieldSpecs": [
{
"dataType": "STRING",
"name": "FA0010000000"
},
{
"dataType": "DOUBLE",
"name": "FA0050000000",
"defaultNullValue": 99
},
{
"dataType": "STRING",
"name": "FA0070180000",
"singleValueField": false
}
],
"timeFieldSpec": {
"incomingGranularitySpec": {
"timeType": "DAYS",
"dataType": "INT",
"name": "time_day"
}
},
"schemaName": "BASIC_0800"
}
