Does it will inspect mysql db called ruicore.app and ruicore.parsed_app?

@modern-nail-74015: to update the schema metadata you need to run the regular sql ingestion (https://datahubproject.io/docs/metadata-ingestion/source_docs/mysql)

this worked successfully when I try to pull schema from mysql

the code you have is just emitting a lineage edge between

<http://ruicore.app|ruicore.app>

and

ruicore.parsed_app

... not connecting to the db and extracting any metadata

How can I push metadata change in python use rest？

sure .. in this case you can build the metadata change event like you are doing in python

I follow the link in instruction，write my own code

lineage_mce_2 = builder.make_lineage_mce(
        [
            builder.make_dataset_urn("mysql", "<http://ruicore.app|ruicore.app>"),
        ],
        builder.make_dataset_urn("mysql", "ruicore.parsed_app"),
    )

    emitter = DatahubRestEmitter("<http://localhost:8080>")
    emitter.emit_mce(lineage_mce_2)

you can look here to figure out how to construct an mce

but the https://github.com/linkedin/datahub/blob/master/metadata-ingestion/examples/library/lineage_emitter_rest.py seems not what I excepted

cool.
