### Prepare a Pull Request
*[INLONG-7072][Manager][Sort] Resource adaptive adjustment for Hudi*
- Fixes #7072
### Motivation
Hudi flink jobs often have unreasonable resource allocation. Too much
allocation will lead to waste of resources, and too little will lead to back
pressure or OOM.
When allocating resources, you first need to determine the concurrency of
the source side to ensure that there is no data backlog in the upstream when
reading. Here is a general configuration situation, such as partitioning by
day, with about 15 billion data per day, and about 50 concurrent
configurations. Other data volumes can be converted appropriately.
After determining the concurrency on the source side, you can configure the
concurrency of write according to the ratio of 1:1.5 or 1:2.
If OOM occurs in the write operator during operation, you can appropriately
add write concurrency and TM memory.
If the following back pressure occurs, the concurrency can be adjusted
according to the consumption difference between source and write. As follows,
there is a difference of about 50W, that is, there is 50W of data that cannot
keep up with the write, and then it can be based on the amount of successfully
written data and the running (used) Time to calculate how much write
concurrency is needed to calculate the difference of 50W.
### Modifications
1. Estimate the parallelism of the source node based on the estimated daily
data volume input by the user at a rate of 1,000 per second per core.
2. Configure write concurrency according to the ratio of 1:1.5 or 1:2
