Differences between this plugin and the Taxonomy_MetaData helper class

[austinjreilly]

Is there a compelling reason why I would use this plugin instead of the Taxonomy_MetaData helper class? In CMB2/CMB2@09d6c56, @jtsternberg writes that this is

Similar to Taxonomy_MetaData, but uses a custom table for taxonomy term meta storage.

Why would I care about using a custom table or not?

Hi @austinjreilly,

There is a discussion you can have a look at. My point is that using a custom table is better both in scalability and "architecture" (if the term works for WordPress).

This is actually a good discussion on the matter: http://wordpress.stackexchange.com/questions/47915/should-i-use-custom-post-types-or-a-custom-database-tables-for-plugin-developmen

First sentence:

You should be skeptical of anyone who says that there is a single "right" way. The right way depends on the situation.

There are pros/cons to both, and different projects will benefit from different solutions.
