Simplified the abstractions to remotedb, a package that
allows clients to use whatever database they can in client
code without having to switch out their code e.g
```go
client, err := remotedb.NewInsecure(":9888")
...
// Just like they'd initialize locally
in := &remotedb.Init{
Name: "test-remote-db",
Type: "leveldb",
Dir: "/tmp/dbs",
}
if err := client.InitRemote(in); err != nil {
log.Fatalf("Failed to initialize the database")
}
v1 := client.Get(k1)
client.Set(k9, dog)
for itr := client.Iterator(a1, z1); itr.Valid(); itr.Next() {
k, v := itr.Key(), itr.Value()
dom := itr.Domain()
...
}
```

remotedb is a package for connecting to distributed Tendermint db.DB
|
|
instances. The purpose is to detach difficult deployments such as
|
|
CLevelDB that requires gcc or perhaps for databases that require
|
|
custom configurations such as extra disk space. It also eases
|
|
the burden and cost of deployment of dependencies for databases
|
|
to be used by Tendermint developers. Most importantly it is built
|
|
over the high performant gRPC transport.
|
|
|
|
remotedb's RemoteDB implements db.DB so can be used normally
|
|
like other databases. One just has to explicitly connect to the
|
|
remote database with a client setup such as:
|
|
|
|
client, err := remotedb.NewInsecure(addr)
|
|
// Make sure to invoke InitRemote!
|
|
if err := client.InitRemote(&remotedb.Init{Name: "test-remote-db", Type: "leveldb"}); err != nil {
|
|
log.Fatalf("Failed to initialize the remote db")
|
|
}
|
|
|
|
client.Set(key1, value)
|
|
gv1 := client.SetSync(k2, v2)
|
|
|
|
client.Delete(k1)
|
|
gv2 := client.Get(k1)
|
|
|
|
for itr := client.Iterator(k1, k9); itr.Valid(); itr.Next() {
|
|
ik, iv := itr.Key(), itr.Value()
|
|
ds, de := itr.Domain()
|
|
}
|
|
|
|
stats := client.Stats()
|
|
|
|
if !client.Has(dk1) {
|
|
client.SetSync(dk1, dv1)
|
|
}
