How to migrate data from MySQL to Memgraph?

Dataset

For this tutorial, we will be working with a MySQL database named users_db that contains two tables, users and user_relationships:

The users table contains four users with their ids and names:

mysql> SELECT * FROM users;
+----+------+
| id | name |
+----+------+
| 0 | Anna |
| 1 | Josh |
| 2 | Lisa |
| 3 | Troy |
+----+------+

Migrating

1. You can migrate this database into Memgraph by running:

build/src/mgmigrate --source-kind=mysql /
--source-host 127.0.0.1 /
--source-port 33060 /
--source-username root /
--source-password mysql /
--source-database=users_db /
--destination-host 127.0.0.1 /
--destination-port 7687 /
--destination-use-ssl=false

2. Run the following query in Memgraph Lab or mgconsole to see the results:

MATCH (n)-[r]-(m) RETURN n,r,m;

The query results should be:

memgraph> MATCH (n)-[r]-(m) RETURN n,r,m;
+--------------------------------+--------------------------------+--------------------------------+
| n | r | m |
+--------------------------------+--------------------------------+--------------------------------+
| (:users {id: 1, name: "Josh"}) | [:user_relationships] | (:users {id: 0, name: "Anna"}) |
| (:users {id: 0, name: "Anna"}) | [:user_relationships] | (:users {id: 1, name: "Josh"}) |
| (:users {id: 3, name: "Troy"}) | [:user_relationships] | (:users {id: 2, name: "Lisa"}) |
| (:users {id: 2, name: "Lisa"}) | [:user_relationships] | (:users {id: 3, name: "Troy"}) |
