Changelog

0.6.7

2022-2-21

  • Use cosmos/rocksdb instead of techbot/rocksdb
  • Add ForceCopmact to goleveldb database

0.6.6

2021-11-08

Important note: Version v0.6.5 was accidentally tagged and should be avoided. This version is identical to v0.6.4 in package structure and API, but has updated the version marker so that normal go get upgrades will not require modifying existing use of v0.6.4.

Version bumps (since v0.6.4)

  • Bump grpc from to 1.42.0.
  • Bump dgraph/badger to v2 2.2007.3.
  • Bump go.etcd.io/bbolt to 1.3.6.

0.6.5

2021-08-04

Important note: This version was tagged by accident, and should not be used. The tag now points to the package-reorg branch so that any existing dependencies should not break.

0.6.4

2021-02-09

Bump protobuf to 1.3.2 and grpc to 1.35.0.

0.6.3

2020-11-10

Improvements

  • [goleveldb] #134 Improve iterator performance by bounding underlying iterator range (@klim0v)

0.6.2

2020-08-27

Bump grpc, badger and goleveldb (see versions in go.mod file)

0.6.1

2020-08-12

Improvements

  • #115 Add a BadgerDB backend with build tag badgerdb (@mvdan)

0.6.0

2020-06-24

Breaking Changes

  • #99 Keys can no longer be nil or empty, and values can no longer be nil (@erikgrinaker)

  • #98 NewDB now returns an error instead of panicing (@erikgrinaker)

  • #96 Batch.Set(), Delete(), and Close() may now error (@erikgrinaker)

  • #97 Iterator.Close() may now error (@erikgrinaker)

  • #97 Many iterator panics are now exposed via Error() instead (@erikgrinaker)

  • #96 The SetDeleter interface has been removed (@erikgrinaker)

Bug Fixes

  • #97 RemoteDB iterators are now correctly primed with the first item when created, without calling Next() (@erikgrinaker)

0.5.2

2020-11-10

Improvements

  • [goleveldb] #134 Improve iterator performance by bounding underlying iterator range (@klim0v)

0.5.1

2020-03-30

Bug Fixes

  • [boltdb] #81 Use correct import path go.etcd.io/bbolt

0.5.0

2020-03-11

Breaking Changes

  • #71 Closed or written batches can no longer be reused, all non-Close() calls will panic

  • [memdb] #74 Iterator() and ReverseIterator() now take out database read locks for the duration of the iteration

  • [memdb] #56 Removed some exported methods that were mainly meant for internal use: Mutex(), SetNoLock(), SetNoLockSync(), DeleteNoLock(), and DeleteNoLockSync()

Improvements

  • [memdb] #53 Use a B-tree for storage, which significantly improves range scan performance

  • [memdb] #56 Use an RWMutex for improved performance with highly concurrent read-heavy workloads

Bug Fixes

  • [boltdb] #69 Properly handle blank keys in iterators

  • [cleveldb] #65 Fix handling of empty keys as iterator endpoints

0.4.1

2020-2-26

Breaking Changes

        • Has(key []byte) (bool, error)

        • SetSync([]byte, []byte) error
        • Delete([]byte) error
        • DeleteSync([]byte) error
        • Iterator(start, end []byte) (Iterator, error)
        • ReverseIterator(start, end []byte) (Iterator, error)
        • Close() error
