Presto connector plugin for Vitess

[!WARNING]: This repo is forked from vitessio/contrib: Vitess contributions

Catalog format (every line is required):

connector.name=vitess  
connection-url=jdbc:mysql://<vtgate ip address>:<vtgate port>/<Vitess keyspace>  
connection-user=<vtgate user>  
connection-password=<vtgate password>  
vitess.vttablet_schema_name=<schema name inside vttablet>
  • Vitess keyspace name is required in the connection URL, otherwise Presto can't access vttablet's information_schema
  • If not explicitly set by -init_db_name_override option or if vttablet is not managing another remote mysqld, vttablet's schema name is by default vt_<keyspace name>
  • This connector cannot list tables using show tables yet.
