Emmanuel T Odeke	5d12e1eb46	remotedb: a client package implementing the db.DB interface 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() ... } ```	7 years ago
Emmanuel T Odeke	1260b75f63	grpcdb: Better readability for docs and constructor names * Added some docs for NewClient, BindServer, server.Init Security level clarified, whether "secure" for https or "insecure" for non-https gRPC connections.	7 years ago
Emmanuel T Odeke	11bee6194a	DB as a service 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) } } ```	7 years ago
