Hello all,

Iv made a few changes in horizon. To be able to use those features, i would also need to change the way the metadata is stored, since im relating to a different backend, in order to be able to process input received from horizon correctly.

So my main question is, how does cinder perform insert, update, delete operations on its mysql database for the data that it receives from a horizon form?

Been stuck on it for a while. Any help would be much appreciated.

Hey @SamYaple, You are right. What i actually meant was how is the metadata for these backends stored, since im already using another backend. I will reframe the above question and have a look at the link that you posted. Hope that helps. Will keep you posted.

What do you mean "the way data is stored"? Cinder is just a wrapper for a backend where your data is actually stored. Cinder can use a few backends, the common ones are LVM, NFS, Ceph.

If your question is about the metadata for these backends, you'll need to either start digging into the code for cinder, or ask a more directed question.
