Connection and Running

This topic describes the specifications you need comply with when you connect to Doris and run Doris tasks.

• Use an ELB to connect to Doris to prevent services interruption when the connected FE is faulty.
• If a hardware fault or a single Doris instance failure occurs, Doris can continue executing running tasks, but newly submitted tasks cannot run. You should enable retry upon failures so that submitted jobs can still run in case of unknow exceptions.
