func (b *Batch) Delete(storeKey, key []byte) error

func (*Batch) Reset ¶

func (b *Batch) Reset() error

func (*Batch) Set ¶

func (b *Batch) Set(storeKey, key, value []byte) error

func (*Batch) Size ¶

func (b *Batch) Size() int

func (*Batch) Write ¶

func (b *Batch) Write() error

func (*Database) Close ¶

func (db *Database) Close() error

func (*Database) Get ¶

func (db *Database) Get(storeKey []byte, targetVersion uint64, key []byte) ([]byte, error)

func (*Database) GetLatestVersion ¶

func (db *Database) GetLatestVersion() (uint64, error)

func (*Database) Has ¶

func (db *Database) Has(storeKey []byte, version uint64, key []byte) (bool, error)

func (*Database) Iterator ¶

func (db *Database) Iterator(storeKey []byte, version uint64, start, end []byte) (corestore.Iterator, error)

func (*Database) NewBatch ¶

func (db *Database) NewBatch(version uint64) (store.Batch, error)

func (*Database) PrintRowsDebug ¶

func (db *Database) PrintRowsDebug()

func (*Database) Prune ¶

func (db *Database) Prune(version uint64) error

Prune removes all versions of all keys that are <= the given version. It keeps the latest (non-tombstoned) version of each key/value tuple to handle queries above the prune version. This is analogous to RocksDB full_history_ts_low.

We perform the prune by deleting all versions of a key, excluding reserved keys, that are <= the given version, except for the latest version of the key.

func (*Database) ReverseIterator ¶

func (db *Database) ReverseIterator(storeKey []byte, version uint64, start, end []byte) (corestore.Iterator, error)

func (*Database) SetLatestVersion ¶

func (db *Database) SetLatestVersion(version uint64) error
