Document the new vector index behavior in the user-facing and developer
docs.
Describe `index_version` as a creation timeuuid stored in
`system_schema.indexes`, clarify that recreating an index changes it
while ALTER TABLE does not, and document that Scylla allows multiple
named vector indexes on the same column while still rejecting unnamed
duplicates.
This folder contains developer-oriented documentation
concerning the ScyllaDB codebase.
We also have a wiki, which contains
additional developer-oriented documentation. There is currently no clear
definition of what goes where, so when looking for something be sure to check
both.
