A 500 row table weighs 47 gigabytes! How to find the reason?

Question

MySQL

Good afternoon.
wp_options (utf8) is 47 gigs and has 500 lines in total. According to my calculations, these lines cannot weigh that much.
Autoincrement is already about 160,000.

Are there any hidden fields in the database? Caching or something like that? Where are these gigabytes of data stored? Count shows all the same 500 lines +/-
Who faced such a problem?

Answer 1

Your table is too fragmented.
login to the server via sssh and do mysqlcheck -o "base name" "table name"
