Hello!

1. The upper limit of the elk connection is limited by the semaphore of the os system, which is related to the semaphore. The semaphore of a system is common, and deploying 1 dn (data node) and 10 dn are different. The construction of a single point can be understood as system resources, with one less, the amount of elk online can be understood in multiples.

2. Resource pool connection reference can be set by referring to the corresponding parameter value of the product document to follow the actual situation of the site.

3. Ds will not be saved automatically. Auto save needs to reopen ds, sql still exists. Ds is automatically saved every 5 minutes.
