MatchQuery is a JSON string that specifies the selection criteria using query operators for the documents to be returned from the collection.

schema [object]

fields [Config]

Because MongoDB does not have the concept of schema, when engine reads MongoDB , it will sample MongoDB data and infer the schema . In fact, this process will be slow and may be inaccurate. This parameter can be manually specified. Avoid these problems.

such as:

schema {
fields {
id = int
key_aa = string
key_bb = string
}
}
