Change the path of the subbucket about bbolt HOT 10 CLOSED

Is it possible that change the path of the subbucket to A/D/C without having to delete and rebuild the subbucket again?

It should be possible to move a sub-bucket into another bucket with a simple program .

@Elbehery are you interested to provide a demo on this?

from bbolt.

yes, on me 👍🏽 🙏🏽

@ahrtr just few questions

• moving sub-buckets inside the b+tree, should also update the internals node, since the key range changes, no ?
• a solution which will hidden from the user, would to delete the sub-bucket and insert it into the dst path, no optimal though

@Elbehery Sorry, i find that the subbucket maybe have other subsubbuckets.

It shouldn't be a problem. Essentially, we just move a subtree in a b+tree to another place, no matter what are included in the sub-tree. The only comment/concern is some methods or functions (used to move the sub-tree) in bbolt may not be public yet, but anyway it's a good topic to learn bbolt.

I started investigating this, and I found an opportunity to refactor, i raised #606

@ahrtr would you kindly assign this to me, i already started working on it 👍🏽

@ahrtr May I ask how things are going？

There is no plan to change bbolt to support the case so far. This ticket is just used as an example for the mentorship program.

@ahrtr What do i need to do to implement it? What things need to be careful?

FYI. #621
