Sergei Petrunia 230bcae7b6 Add a limited support for iteration bounds into BaseDeltaIterator (#5403) ... Summary: For MDEV-19670: MyRocks: key lookups into deleted data are very slow BaseDeltaIterator remembers iterate_upper_bound and will not let delta_iterator_ walk above the iterate_upper_bound if base_iterator_ is not valid anymore. == Rationale == The most straightforward way would be to make the delta_iterator (which is a rocksdb::WBWIIterator) to support iterator bounds. But checking for bounds has an extra CPU overhead. So we put the check into BaseDeltaIterator, and only make it when base_iterator_ is not valid. (note: We could take it even further, and move the check a few lines down, and only check iterator bounds ourselves if base_iterator_ is not valid AND delta_iterator_ hit a tombstone).
