DBeaver

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 "kamu" as username and password
   • In Driver properties tab add user property:

     useEncryption=false
