Thank you very much for your explanation.
i just discovered that my system is not using any rowstore table. But when I check in information_schema.MV_GLOBAL_STATUS, Alloc_variable and Alloc_table_primary still have large values and cause Alloc_table_memory to reach maximum_table_memory. I think that’s why my system is having error.
I want to know if these two variables serve anything other than the rowstore table and what is the solution to free this memory.
I look forward to hearing from you.
