We need to handle range keys in SSTs, e.g. for backup/restore and Raft snapshots. In order to do this, we need support for range keys in SSTWriter and sstIterator. This involves implementing the range key methods from the Writer and SimpleMVCCIterator interfaces such that they comply with the interface, and adding tests (iterator tests via TestMVCCHistories).

// ExperimentalPutMVCCRangeKey implements the Writer interface. |

func (fw *SSTWriter) ExperimentalPutMVCCRangeKey(MVCCRangeKey, MVCCValue) error { |
|
panic("not implemented") |
|
} |
|
|
|
// ExperimentalClearMVCCRangeKey implements the Writer interface. |
|
func (fw *SSTWriter) ExperimentalClearMVCCRangeKey(MVCCRangeKey) error { |
|
panic("not implemented") |
|
} |

// ExperimentalClearAllMVCCRangeKeys implements the Writer interface. |
|
func (fw *SSTWriter) ExperimentalClearAllMVCCRangeKeys(roachpb.Key, roachpb.Key) error { |
|
panic("not implemented") |
|
} |
|
// HasPointAndRange implements SimpleMVCCIterator. |

func (r *sstIterator) HasPointAndRange() (bool, bool) { |

func (r *sstIterator) RangeBounds() roachpb.Span { |

panic("not implemented") |

// RangeKeys implements SimpleMVCCIterator. |

func (r *sstIterator) RangeKeys() []MVCCRangeKeyValue { |
