示例1: ClearData
// ClearData removes all persisted items stored in the cache.
func (sc *AbortCache) ClearData(e engine.Engine) error {
b := e.NewBatch()
defer b.Close()
_, err := engine.ClearRange(b, engine.MakeMVCCMetadataKey(sc.min()), engine.MakeMVCCMetadataKey(sc.max()))
if err != nil {
return err
}
return b.Commit()
}示例2: ClearData
// ClearData removes all persisted items stored in the cache.
func (sc *AbortCache) ClearData(e engine.Engine) error {
_, err := engine.ClearRange(e, engine.MakeMVCCMetadataKey(sc.min()), engine.MakeMVCCMetadataKey(sc.max()))
return err
}示例3: ClearData
// ClearData removes all items stored in the persistent cache. It does not alter
// the inflight map.
func (rc *ResponseCache) ClearData(e engine.Engine) error {
p := keys.ResponseCacheKey(rc.rangeID, nil) // prefix for all response cache entries with this range ID
end := p.PrefixEnd()
_, err := engine.ClearRange(e, engine.MVCCEncodeKey(p), engine.MVCCEncodeKey(end))
return err
