Hello,  
I’m trying to test using Percona 8.0.15.5 however when used with default settings, it just fails with Operation aborted: Failed to acquire lock due to max\_num\_locks limit" from ROCKSDB.

Is there any good guideline regarding what parameters have to be tuned to be able to successfully load large tables? The table that I am trying to change in my case is only 10GB in size. Also are there any known limits regarding large per node sizes for which special finetuning is required? I have a 150TB database that I’d like to test…
