why the graph is not modified on bulk delete?

[msk-apk]

On seeing the code, bulk delete just deletes the data from node. Graph is not modified on bulk delete. Am i missing anything? Will there be any limitation as the neighbour id list is not modified? Do we need to implement the algorithm for delete as in fresh diskann?

any one knows the reason behind not implementing fresh diskann for delete?

The queries remain correct because we ignore deleted nodes at query-time. But it is true we don't free disk space. Ideally such cleanup would be done in the VACUUM process but it hasn't yet been implemented

ok that clears my question.
