To mount a MySQL database into the Splitgraph engine using mysql_fdw, run:

$ sgr mount mysql_fdw local_schema -c username:password@host:port -o@- <<EOF
{
    "remote_schema": "remote_schema",
    "tables": ["table_1"],
}

This will mount a MySQL schema remote_schema into a local schema schema_name on the Splitgraph engine. Note that if your MySQL server is running on localhost and you wish to access it over a TCP connection, you should use 127.0.0.1 instead of localhost as the host.

"tables" can be omitted (in which case all tables in remote_schema will be mounted into local_schema).

You can also pass a dictionary of tables and their schema as tables. This will override the schema that's inferred by IMPORT FOREIGN SCHEMA. For example:

{
    "tables": {
        "table_1": {
            "col_1": "integer",
            "col_2": "text"
        }
    }
}

To snapshot the table, making it part of an actual Splitgraph image, use the sgr import command.
