¡PLEASE, reduce the usage of postmeta table!

Describe the Problem

It is crazy to get a 700MB table of postmeta

Propose a Solution

Use external files, or compressed information, or optimize queries

But it is not a good experience to receive such errors:
PHP Fatal error: Out of memory (allocated 1874042880 bytes) (tried to allocate 61440 bytes) in /home/customer/www/.../public_html/wp-includes/class-wpdb.php on line 2323
