Vaibhav Joshi commented on CALCITE-5581:
----------------------------------------
Thanks [~stoty]
Based on your inputs I am planning to add following connection properties.
*HTTP_CONNECTION_TIMEOUT* - Timeout in milliseconds. Default will be 3 minutes
( retained from the old implementation). Also this will be generic property,
which can be set irrespective of LB configs.
*LB_FAILOVER_RETRIES* - Number of retries we need to do during failover. We
will have a retry logic to try different URLs when some connection attempt is
failed. By default we will do 3 retries. This Config will be applicable only
when USE_CLIENT_SIDE_LB is true.
Please let me know if this looks okay.
