When dealing with a large number of tasks, the default execution queue
size is 1024. This can lead to tasks being dropped if the queue becomes
full.
eg
`dispatch instant task failed, job id is xxx`
To address this, you can add the parameters `insert_task_queue_size` and
`mtmv_task_queue_size` in the `fe.conf` configuration file. These
parameters must be set to a power of 2.
**Keep in mind, increasing this value is recommended only when thread
resources are limited; otherwise, you should consider increasing the
number of task execution threads.**
