步骤
1.MongoDB数据导出json - MongoDB的全量数据 --json
2.Duckdb读取json
create table duck_t1 as SELECT * FROM read_json_auto('t1.json');
3.Duckdb映射远端MySQL mysql_dat库，并起一个数据库别名 mysql_alias
ATTACH 'host=192.168.1.1 user=admin password=123456 port=3306 database=mysql_dat' AS mysql_alias (TYPE mysql_scanner);
4.Duckdb中操作mysql数据库
create table mysql_alias.t1 as SELECT * EXCLUDE('_id') FROM me.t1;
