TiDB

MySQL-compatible distributed SQL database.

Connection fields

Field	Required	Description
`host`	Yes	Hostname or IP address of the TiDB cluster's SQL endpoint.
`port`	No	Defaults to 3306.
`user`	Yes	Username to authenticate with.
`password`	No	Not enforced by the connector, but almost every real deployment requires one — leave it blank only against a server configured to allow passwordless auth.
`db`	Yes	Database name to connect to.

TiDB speaks the MySQL wire protocol, so it runs on the same connector code as MySQL/MariaDB — only the stored type name differs.

{
  "host": "tidb-cluster.internal.example.com",
  "port": 4000,
  "user": "arcodash_reader",
  "password": "••••••••",
  "db": "analytics"
}

TiDB's default SQL port is 4000, not MySQL's 3306 — the connector's own default is still 3306, so set port explicitly for a standard TiDB deployment.
