Map operations

Example: user with nested address map

// Store nested structure
userData := map[any]any{
    "name": "John Doe",
    "address": map[string]any{
        "street": "123 Main St",
        "city":   "San Francisco",
        "zip":    "94102",
    },
}

key, _ := as.NewKey("app", "users", "user123")
_, err := client.Operate(nil, key,
    as.MapPutItemsOp(as.DefaultMapPolicy(), "user", userData),
)

// Get nested city
ctx := []*as.CDTContext{
    as.CtxMapKey(as.StringValue("address")),
}

record, err := client.Operate(nil, key,
    as.MapGetByKeyOp("user", "city", as.MapReturnType.VALUE, ctx...),
)

results := record.Bins["user"].(map[any]any)
city := results["city"].(string)
fmt.Println("City:", city)  // Output: City: San Francisco

Example: multi-level configuration

// Store nested configuration
config := map[any]any{
    "database": map[string]any{
        "primary": map[string]any{
            "host": "db1.example.com",
            "port": 3306,
        },
        "replica": map[string]any{
            "host": "db2.example.com",
            "port": 3306,
        },
    },
}

key, _ := as.NewKey("app", "config", "production")
_, err := client.Operate(nil, key,
    as.MapPutItemsOp(as.DefaultMapPolicy(), "config", config),
)

// Get primary database host
ctx := []*as.CDTContext{
    as.CtxMapKey(as.StringValue("database")),
    as.CtxMapKey(as.StringValue("primary")),
}

record, err := client.Operate(nil, key,
    as.MapGetByKeyOp("config", "host", as.MapReturnType.VALUE, ctx...),
)

host := record.Bins["config"].(string)
fmt.Println("Primary DB host:", host)
