Appending in FlatBuffer
0
We already are using a flatbuffer with a similar scheme
namespace potter;
union Magic { Weapon, Wand }
table Weapon {
name:string;
power:int;
}
table Wand {
make:string;
animal:string;
}
table MagicHolder {
name:string;
age:int;
magic:Magic;
}
root_type MagicHolder;
Now, if we want to add two things.
level:stringin theMagicHolder
- Under the
Wandakey:valuetype, wherekey:string, andvaluecan be eitherstring or int or float or bool
What I’m trying is
table MagicHolder {
name:string;
age:int;
level:string; /*new addition*/
magic:Magic;
}
table KeyValue {
key:string;
vint:int;
vfloat:float;
vbool:bool;
vstring:string;
vtype:string; /* since I cannot differentiate between bool set or not, trying to store type here */
}
table Wand {
make:string;
animal:string;
kv:KeyValue;
}
Is this the best approach? What would be the pros/cons.. Any other recommended ways to do this new additions more efficiently

Level string needs to be at the end of table. We can't evolve schema safely by inserting fields in between.

I also thought so.. however, the last value is of type Magic, which is a union.. so couldlevelstill be after a union (which is of different type)

Can create a union of all the value types... Kept in KeyValue

Yes you may and should add new entries (union or not) at the end of table.
