Suppose inputData contains Avro data with the following schema:
| No Format |
|---|
{
"typename" : "recordImpressionSetEvent",
"nametype" : "ImpressionSetEventrecord",
"fields" : [
{
"name" : "pageNumber",
"type" : [ "int", "null" ]
},
{" {
"name" : "impressionDetails",
"type" :{"type": "record", {
"name" : "ImpressionDetailsRecord",
"fields "type" : "record",
"fields" : [
{
"name" : "id", "type":"int"},
{"name":"type",
"type":{"type":"enum", "name":"ItemType",
"symbols":["person", "job", "group", "company", "nus", "news", "ayn"]}},
{"name":"details","type":{"type":"map","values":"string" }
]}
}
"type" : "int"
},
{
"name" : "type",
"type" : {
"type" : "enum",
"name" : "ItemType",
"symbols" : [ "person", "job", "group", "company", "nus",
"news", "ayn" ]
}
},
{
"name" : "details",
"type" : {
"type" : "map",
"values" : "string"
}
}
]
}
}
]
}
|
AvroStorage will construct two maps. One maps from type name to schema as
type name | schema | ||
ImpressionSetEvent | the whole schema | ||
