1. Add parallel number property in fragment
2. Parallel number will be init in contrustor of fragment
3. Async plan will use the default value while sync plan will use the parallelExecInstanceNum of SessionVariable
1. Some previous doris version may cause some invalid replica last failed version.
2. Also modify the CREATE TABLE help doc, remove row storage type and random distribution.
1. The balance task does not taking storage medium into account.
2. When repairing tablet with version incomplete, tablet with replica (2-xx), (2-xx), (2-0) can't be handled.
3. Show proc stmt may throw null pointer exception when all replicas are missing.
1. Limit the number of balance tablet selection. The number of
tablet selection should be less than the low load path number.
2. Limit the max number of balance task to 500.
* Change routine load task sheduler interval to 0
1. change routine load task scheduler interval to 0
2. init progress when routine load scheduler
3. add unit test and function test of routine load scheduler and task commit
* Add checker of custom kafka partition
1. need scheduler to need schedule
2. add checker of custom kafka partition when create routine load job
3. fix unit test error
1. The method assignConjuncts in SingleNodePlanner could not allocate constant predicate correctly.
2. It use e.isBoundByTupleIds() which always return ture whatever tupleIds when e is a constant predicate.
3. I use PlanNode assignConjuncts instead of SingleNodePlanner's.
When Backend report unused replica, which means this replica
is bad, Frontend should set this replica as bad and repair it.
Also, when a disk is reported unused, Frontend should mark this
disk as OFFLINE. And no more replica will be assigned to this
disk.
We also add 3 new metrics: disk_state, tablet_num and scheduled_tablet_num
on Frontend to monitor the disk state and number of tablet on each Backend.
