Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/11930 The patch cleans up and refactors the logic in/around `WriteBatchWithIndexInternal` a bit as groundwork for further changes. Specifically, the class is turned back into a stateless collection of static helpers (which is the way it was before PR 6851). Note that there were two apparent reasons for introducing this instance state in PR 6851: a) encapsulating `MergeContext` and b) resolving objects like `Logger` and `Statistics` based on a variety of handles. However, neither reason seems justified at this point. Regarding a), the `MultiGetFromBatchAndDB` logic passes in its own `MergeContext` objects via a second set of methods that do not use the member `MergeContext`. As for b), `Logger` and friends are only needed for Merge, which is only supported if a column family handle is provided; in turn, the column family handle enables us to resolve all the necessary objects without the need for any other handles like `DB` or `DBOptions`. In addition to the above, the patch changes the type of `BaseDeltaIterator::merge_result_` to `std::string` from `PinnableSlice` (since no pinning is ever done) and makes some other small code quality improvements.
