Description

mongo data

db.cdc_test.insertOne({
    c_string: "Hello, MongoDB!",
    c_bool: true,
    c_int: 123456,
    c_long: NumberLong("1234567890123456789"),
    c_double: 123.45,
    c_decimal: new Decimal128("12345.67"),
    c_date: new Date(),
    c_timestamp: new Timestamp(1334567890, 1),
    c_object: { "key1": "value1", "key2": "value2" },
    c_array: ["str1","str2", 789]
});

There are 2 questions

1. The timestamp type of mongo becomes string in doris, and when written to doris, it becomes like this

2. In the MongoDBType.toDorisType method, the array type of mongo is actually collected as List. And the returned array type should be array.
