kill-mysql-query interactively shows long running queries in MySQL database and provides option to kill them one by one.

👉 Great for firefighting situations 🔥🚨🚒

It can connect to MySQL server as configured, can use SSH Tunnel if necessary, and let you decide which query to kill. By default queries running for more than 10 seconds will be marked as long running queries, but it can be configured.

[MySQL]
  mysql_host = ""
  mysql_port = 3306
  mysql_username = ""
  mysql_password = ""

  # hosted_in_aws_rds: Optional.
  #
  # Uses `CALL mysql.rds_kill()` instead of `kill` command.
  # Useful in RDS databases or replica where
  # `mysql_username` may not have privilege to use `kill`
  hosted_in_aws_rds = false

  # db: Optional.
  #
  # If provided, filter out long running
  # queries from other databases
  db = ""

[ssh_tunnel]
  use_ssh_tunnel = false
  ssh_host = ""
  ssh_port = 22
  ssh_username = ""
  ssh_password = ""

  # ssh_private_key takes priority over ssh_password
  # if both are provided
  ssh_private_key = ""

  # ssh_key_passphrase: Optional.
  ssh_key_passphrase = ""

[long_running_query]
  # Default is 10 seconds.
  # `kill-mysql-query` will only list running queries
  # those are being executed for more than or equal to
  # this value.
  timeout_second = 10
