Indexing a reference column
Pergunta
Say I have a reference table like languages
with only 20 records. Is it worth indexing a field like language_code
(e.g. en
, es
) that's frequently used in queries? I'm wondering if an efficient server would effectively be indexing columns like this automatically.
This is specifically for MariaDB with InnoDB engine.
