Superset accesses mysql and impala

     Superset is an open source data analysis and visualization platform (formerly known as Caravel, Panoramix) opened by Airbnb (a well-known online short-term rental company). The main features of this tool are self-service analysis, custom dashboards, analysis results visualization (export), user /role permission control, and also integrates a SQL editor, which can perform SQL editing and querying, etc. It was originally used to support Druid's visual analysis, and later developed to support many relational databases and big data computing frameworks, such as: mysql, oracle, Postgres, Presto, sqlite, Redshift, Impala, SparkSQL, Greenplum, MSSQL.
