Whoops, conflict with last bors r- |
This patch adds a parameter `UseExperimentalRangeTombstone` for `DeleteRange`, which deletes the span using an MVCC range tombstone. This must only be called after checking `storage.CanUseExperimentalMVCCRangeTombstones()`, which ensures the `ExperimentalMVCCRangeTombstones` version gate and `COCKROACH_EXPERIMENTAL_MVCC_RANGE_TOMBSTONES` environment variable are set. Did I mention that MVCC range tombstones are experimental? They are currently under active development, and are not respected by the KV or MVCC APIs, nor are they persisted. This patch simply sets up the plumbing for it. Release note: None

76921: storage: revert experimental MVCC range tombstones r=aliher1911 a=erikgrinaker This reverts most of #76131, #76203, and #76478 -- except minor changes that were unrelated to the range tombstones themselves. This leaves a gap for cluster version `Internal:78` -- I think that's probably fine, but I've left a comment. Co-authored-by: Erik Grinaker <grinaker@cockroachlabs.com>

77762: batcheval: add range tombstone support for `DeleteRange` r=aliher1911 a=erikgrinaker This patch adds the parameter `UseExperimentalRangeTombstone` for `DeleteRange`, which deletes the span using an MVCC range tombstone. The new version gate `MVCCRangeTombstones` must be checked before using it. `storage.ExperimentalMVCCDeleteRangeUsingTombstone()` is added to carry out the actual deletion. This is a bare-bones implementation to allow writing range keys via the KV API for testing and development purposes. It has significant shortcomings, and will be fleshed out at a later time. Touches #70415. Replaces #76203. Release note: None Co-authored-by: Erik Grinaker <grinaker@cockroachlabs.com>
