After enabling authentication, able to login to SQLLine with passing the superuser i.e. ignite credentials. After logging I can see schemas like IGNITE, PUBLIC etc. Now, how I connect to any of the schema existing in the Ignite Cluster? Can I grant particular user to access the particular schema and does ignite super user has full access to any schemas?
Ignite does not have ACLs right now. Successful authentication means you are allowed to see and change everything.
GridGain, which is built on top of Ignite, has some advanced security, though.
