If the physical machine’s memory configuration is relatively low and running multi-table joins causes insufficient memory, how should it be handled?

Can the SQL be further optimized?
If it cannot be further optimized, you can consider using disk storage by setting the following parameters:

oom-use-tmp-storage

tmp-storage-path

tmp-storage-quota

Currently, there is no documentation stating that external storage is supported. If SQL optimization has been done to the utmost, it is recommended to add a physical machine.
