      public static final String FAILED_HOST_RECONNECT_DELAY_SECS_KEY
      The driver marks a server as failed with a timestamp, when it cannot connect to it. Later, whenever it refreshes the server list via yb_servers(), if it sees the failed server in the response, it marks the server as UP only if the time specified via this property has elapsed since the time it was last marked as a failed host.

    • DEFAULT_FAILED_HOST_TTL_SECONDS

      public static final int DEFAULT_FAILED_HOST_TTL_SECONDS
      The default value should ideally match the interval at which the server-list is updated at cluster side for yb_servers() function. Here, kept it 5 seconds which is not too high (30s) and not too low (1s).
