DBeaver is a great free database exploration tool. It can be connected to kamu using a JDBC driver. In this setup:
  • kamu runs an Arrow Flight SQL server - a high-performance protocol for data transfer
  • DBeaver loads a special JDBC driver - a Java software module that implements an abstract database interface
  • JDBC driver translates DBeaver’s commands into efficient Flight SQL calls in kamu
To connect DBeaver to kamu follow these simple steps:
  1. Downlaod the latest Flight SQL JDBC Driver
  2. Add a new database driver in DBeaver by following these steps
    • For class name use: 
      org.apache.arrow.driver.jdbc.ArrowFlightJdbcDriver
    • For URL template use: 
      jdbc:arrow-flight-sql://{host}:{port}
    • In libraries add the driver’s .jar file you just downloaded
  3. Run kamu Flight SQL server in a desired workspace: 
    kamu sql server --flight-sql --address 127.0.0.1 --port 50050
  4. Create a new connection in DBeaver using the driver you created:
    • Specify host and port, e.g. 127.0.0.1:50050
    • Use "anonymous" as username and password or specify a token for authentication
    • In Driver properties tab add user property: 
      useEncryption=false
