Drupal 8.x

I have a problem when I delete huge data via Rest API.

Problem:

DB size has increased when I had deleted over 300,000 contents via Rest API. DB size has increased from 1.8GB to 7GB.

I checked what file has increased. A file "/var/lib/mysql/ibdata1" has increased.

What I want to do:

I want to modify a program that use Rest API or change server settings so that DB size will not increase. But I don't know how I can do it.

If someone know the solution, could you tell me the solution?

Hi, we are considering to migrate this site: http://www.meollo.net from woocommerce, to the Drupal Commcerce, for SEO reasons, but in drupal 8, i´d like to do some questions:

• There is a module to import/export products their producs and content?
• Is the version 8 of DC ready? i can´t see de profile, only to install the modules?

Thanks very much.

I just learned that the pdfs that I've uploaded to the highest level of my website structure are accessible by url  even though a login is needed for my site.  How can I make these files private?

I am looking to achieve the next functionality: 

I have a content type about fruits, I've added an autocomplete taxonomy field to the content type with the possibility to register new taxonomy.

I would like to achieve some taxonomy depth.

An example would be: I input in the field: apple, fresh, green

When I go to the taxonomy vocabulary fruits I would like to have the taxonomy depth like this:

Szenario:
A view with format content teaser (not fields).

What I want:
exposed combine fields filter on the title and description field of the content types.

Reasons:
For styling reasons it's important the view format is "content" and not "fields". So I don't want and can't change that. I don't want to program a own filter plugin for this request. Because the function actually already exists. I simply can not select the fields via the UI.

when i am creating a new content type with image field, the image alternative text showing error message .    "This value should be of the correct primitive type." the image doesn't showing in the view . how can i solve the problem ?
