Fixes https://github.com/tendermint/tendermint/issues/1162 Databases as a service! Can now access Databases as a remote service via gRPC for performance and easy deployment. The caveat is that each service is stateful in regards to the DB i.e. each unique service uses only one unique DB but nonetheless multiple clients can access it. A full standalone example ```go package main import ( "bytes" "context" "log" grpcdb "github.com/tendermint/tmlibs/grpcdb" protodb "github.com/tendermint/tmlibs/proto" ) func main() { addr := ":8998" go func() { if err := grpcdb.BindRemoteDBServer(addr); err != nil { log.Fatalf("BindRemoteDBServer: %v", err) } }() client, err := grpcdb.NewClient(addr, false) if err != nil { log.Fatalf("Failed to create grpcDB client: %v", err) } ctx := context.Background() // 1. Initialize the DB in := &protodb.Init{ Type: "leveldb", Name: "grpc-uno-test", Dir: ".", } if _, err := client.Init(ctx, in); err != nil { log.Fatalf("Init error: %v", err) } // 2. Now it can be used! query1 := &protodb.Entity{Key: []byte("Project"), Value: []byte("Tmlibs-on-gRPC")} if _, err := client.SetSync(ctx, query1); err != nil { log.Fatalf("SetSync err: %v", err) } query2 := &protodb.Entity{Key: []byte("Project")} read, err := client.Get(ctx, query2) if err != nil { log.Fatalf("Get err: %v", err) } if g, w := read.Value, []byte("Tmlibs-on-gRPC"); !bytes.Equal(g, w) { log.Fatalf("got= (%q ==> % X)\nwant=(%q ==> % X)", g, g, w, w) } } ```
