MySQL 1114 Error, Table /tmp/#sql is full - mysql

Question

I am trying to run TPC-H queries in MySQL server.
Currently, I am using 8.0.23 version (The error did not appear when I used 8.0.19 somehow).
Benchmark size of TPC-H is 10 GB.
I get this error (1114 Error, The table /tmp/#sql~~~ is full) when I submit multiple queries at the same time using 8 threads. There is a chance that identical or similar queries submitted at the same time using different threads.
However, when I just submit a single query in MySQL shell, then it returns a result without the error.
This is the query (there are other queries that raise the same error.)

I checked this thread,
error while executing sql file (ERROR 1114 mysql table is full)
However, It does not help. Here is the list that I checked from the link above.
I have enough disk space.
I increased the size of max_heap_table_size and tmp_table_size as below.
I restarted MySQL server.
innodb_data_file_path is set with autoextend. So, I expect it to extend automatically.
I also checked that my tmpdir is set properly and there is enough disk space.
Here are my MySQL configurations.
innodb_buffer_pool_size=16GB
select ##innodb_buffer_pool_size; -> 17179869184
select ##max_heap_table_size; -> 2147483648
select ##tmp_table_size; -> 2147483648
+-----------------------+------------------------+
| Variable_name | Value |
+-----------------------+------------------------+
| innodb_data_file_path | ibdata1:10M:autoextend |
+-----------------------+------------------------+
Any suggestions will be appreciated. Thanks for reading.

Answer 1

It turns out, I need to change temptable_max_ram (default is 1 GB) since MySQL uses TempTable as default.
If I set internal_tmp_mem_storage_engine as MEMORY (from TempTable), then changing tmp_table_size, max_heap_table_size is fine.
