In Drupal8, what purpose does the key_value_expire table data serve? Can that be excluded from a database backup?
I ask because, during development, I backup the database using "drush sql-dump --ordered-dump" and exclude tables like "cache*", but after making a few minor content changes in a node/page (did not create a revision) and re-dumping the database, git diff is saying that all of the data in the key_value_expire table changed.
key_value_expire is one of the larger tables in Drupal, in terms of # of rows of data, so it will balloon the storage requirements for Git if the data in this table changes completely for every minor change on the site.
Also, is there a detailed explanation of the functionality/purpose of each Drupal table?
Thank you very much in advance.
