Tendermint Common

remotedb is a package for connecting to distributed Tendermint db.DB instances.

See DB interface documentation for more information.

IteratePrefix is a convenience function for iterating over a key domain restricted by prefix.

NewDB creates a new database of type backend with the given name.

NewPrefixDB lets you namespace multiple DBs within a single DB.

BoltDBBackend represents bolt (uses etcd's fork of bolt - github.com/etcd-io/bbolt) - EXPERIMENTAL - may be faster is some use-cases (random reads - indexer) - use boltdb build tag (go build -tags boltdb).

CLevelDBBackend represents cleveldb (uses levigo wrapper) - fast - requires gcc - use cleveldb build tag (go build -tags cleveldb).

FSDBBackend represents filesystem database - EXPERIMENTAL - slow.

GoLevelDBBackend represents goleveldb (github.com/syndtr/goleveldb - most popular implementation) - pure go - stable.

MemDBBackend represents in-memoty key value store, which is mostly used for testing.

It's slow.

Batch Close must be called when the program no longer needs the object.

DBs are goroutine safe.

Usage: var itr Iterator = ..
