Issue https://github.com/scylladb/scylla/issues/7019 describes a problem of an ever-growing map of temporary values stored in query_options. In order to mitigate this kind of problems, the storage for temporary values is moved from an external data structure to the value views itself. This way, the temporary lives only as long as it's accessible and is automatically destroyed once a request finishes. The downside is that each temporary is now allocated separately, while previously they were bundled in a single byte stream.
