dmgcodevil opened a new issue #3025:
URL: https://github.com/apache/iceberg/issues/3025
Why Iceberg overrides schema fields ids for nested structs. For example in
my schema struct field 'LAST_TRADE_PRICE' has id 53, however in metadata json
it's "id" : 49
Shema:
```java
Types.NestedField.optional(53, LAST_TRADE_PRICE, Types.StructType.of(
Types.NestedField.required(54, PRICE,
Types.DoubleType.get()),
Types.NestedField.required(55, YIELD,
Types.DoubleType.get()),
Types.NestedField.required(56, DISCOUNT,
Types.DoubleType.get()),
Types.NestedField.required(57, SCORE,
Types.IntegerType.get())
)),
``
metadata json:
```json
"id" : 49,
"name" : "last_trade_price",
"required" : false,
"type" : {
"type" : "struct",
"fields" : [ {
"id" : 56,
"name" : "price",
"required" : true,
"type" : "double"
}, {
"id" : 57,
"name" : "yield",
"required" : true,
"type" : "double"
}, {
"id" : 58,
"name" : "discount",
"required" : true,
"type" : "double"
}, {
"id" : 59,
"name" : "score",
"required" : true,
"type" : "int"
} ]
}
}
```
Is it possible to preserve original ids ?
