ring_position::min() is noexcept since 6d7ae4e So no need to call it outside of the critical noexcept block. Signed-off-by: Benny Halevy <bhalevy@scylladb.com>
Currently the cache updaters aren't exception safe yet they are intended to be. Instead of allowing exceptions from `external_updater::execute` escape `row_cache::update`, abort using `on_fatal_internal_error`. Future changes should harden all `execute` implementations to effectively make them `noexcept`, then the pure virtual definition can be made `noexcept` to cement that. Fixes scylladb#15576 Signed-off-by: Benny Halevy <bhalevy@scylladb.com>
