CQL data type for storing an array of object

问题

I need to store an array of objects in a Cassandra DB column, for example, I may have a table that has a column named people, which would hold an array of objects:

   [
        {
            name: one,
            age: 1
        },
        {
            name: two,
            age: 2
        }
    ]

However, looking at the docs, I can't find anything that would be a good data type for this except for people set<blob> but I'm wondering if there is something more explicit.

回答1:

You can use user defined type (UDT)

Create a UDT Type :

CREATE TYPE people (
    name text,
    age int
);

Now declare the type of people field :

people set<frozen <people>>
