medline-ghost-demo

Demo repo to show functionality of gh-ost to clients

1. run docker compose up to create a pair of mysql 8.0 servers with distinctly configured server_id's (needed for row based replication)
2. run ./scripts/initial-setup.sh to create a user for replication, configure the master/slave to allow replication, and start replication
3. run ./scripts/init-seeds.sh to create a generic users table, and seed with randomly generated records
4. [todo] execute gh-ost targeting our local environment, as "Test on replica"
   • [todo] verify new table has changes made, and has expected records
   • docs here
5. [todo] execute gh-ost targeting our local environment, as "Migrate on replica"
   • [todo] verify ghost table is gone, and replication is still continuing
