What is Database instance?
The complete running environment providing the database service. This is usually denoted by a host:port pointing to the running instance. When people talk about MySQL/PostgreSQL instance, they usually refer to the database instance. A single database instance can host many databases. Bytebase has an instance concept which is a 1:1 mapping to this instance definition. Instance in Bytebase always belongs to a particular environment. Bytebase also stores the database schema migration history on the instance itself.External reference
