## Proposed changes Add a keep alive feature for Doris shuffle, when a shuffle sink's BE process is dead or restart, shuffle receiver can't receive data forever, but it can not be cancelled until query timeout. So we need introduce a shuffle keep alive feature, the shuffle sink send data periodically even no data is produced. When no data produced, shuffle sink send a empty block to shuffle receiver sink is alive and just wait. Shuffle receiver could cancel itself when no signal is received for a timeout. -- This is an automated message from the Apache Git Service.
