  • v0.10.0 Changes

    • โšก๏ธ pubsub: Subscription.ModifyPushConfig replaced with Subscription.Update.

    • pubsub: Subscription.Receive now runs concurrently for higher throughput.

    • ๐Ÿ—„ vision: is deprecated. Use instead.

    • ๐ŸŒ translation: now stable.

    • ๐Ÿ‘€ trace: several changes to the surface. See the link below.

  • v0.9.0 Changes

    • pubsub: Replace

      sub.ModifyPushConfig(ctx, pubsub.PushConfig{Endpoint: ""})


    sub.Update(ctx, pubsub.SubscriptionConfigToUpdate{
        PushConfig: &pubsub.PushConfig{Endpoint: ""},
    • trace: traceGRPCServerInterceptor will be provided from *trace.Client. Given an initialized *trace.Client named tc, instead of

      s := grpc.NewServer(grpc.UnaryInterceptor(trace.GRPCServerInterceptor(tc)))


    s := grpc.NewServer(grpc.UnaryInterceptor(tc.GRPCServerInterceptor()))
    • trace trace.GRPCClientInterceptor will also provided from *trace.Client. Instead of

      conn, err := grpc.Dial(srv.Addr, grpc.WithUnaryInterceptor(trace.GRPCClientInterceptor()))


    conn, err := grpc.Dial(srv.Addr, grpc.WithUnaryInterceptor(tc.GRPCClientInterceptor()))
    • ๐Ÿšš trace: We removed the deprecated trace.EnableGRPCTracing. Use the gRPC ๐Ÿ“ฆ interceptor as a dial option as shown below when initializing Cloud package clients:

      c, err := pubsub.NewClient(ctx, "project-id", option.WithGRPCDialOption(grpc.WithUnaryInterceptor(tc.GRPCClientInterceptor())))
      if err != nil {
  • v0.8.0 Changes

    • ๐Ÿ“ฆ profiler package added.
    • storage:
      • Retry Objects.Insert call.
      • Add ProgressFunc to WRiter.
    • pubsub: breaking changes:
      • Publish is now asynchronous (announcement).
      • Subscription.Pull replaced by Subscription.Receive, which takes a callback (announcement).
      • Message.Done replaced with Message.Ack and Message.Nack.
  • v0.7.0 Changes

    • ๐Ÿš€ Release of a client library for Spanner. See the blog ๐Ÿš‘ post. Note that although the Spanner service is beta, the Go client library is alpha.
  • v0.6.0 Changes

    • ๐Ÿš€ Beta release of BigQuery, DataStore, Logging and Storage. See the blog post.

    • bigquery:

      • struct support. Read a row directly into a struct with RowIterator.Next, and upload a row directly from a struct with Uploader.Put. ๐Ÿ“š You can also use field tags. See the [package documentation][cloud-bigquery-ref] for details.
      • The ValueList type was removed. It is no longer necessary. Instead of go var v ValueList ... it.Next(&v) .. use
       var v []Value
       ... it.Next(&v) ...
    • Previously, repeatedly calling RowIterator.Next on the same []Value or ValueList would append to the slice. Now each call resets the size to zero first.

    • Schema inference will infer the SQL type BYTES for a struct field of type []byte. Previously it inferred STRING.

    • The types uint, uint64 and uintptr are no longer supported in schema inference. BigQuery's integer type is INT64, and those types may hold values that are not correctly represented in a 64-bit signed integer.

  • v0.5.0 Changes

    • bigquery:
      • The SQL types DATE, TIME and DATETIME are now supported. They correspond to the Date, Time and DateTime types in the new package.
      • Support for query parameters.
      • Support deleting a dataset.
      • Values from INTEGER columns will now be returned as int64, not int. This will avoid errors arising from large values on 32-bit systems.
    • datastore:
      • Nested Go structs encoded as Entity values, instead of a flattened list of the embedded struct's fields. This means that you may now have twice-nested slices, eg. go type State struct { Cities []struct{ Populations []int } } See the announcement for more details.
      • Contexts no longer hold namespaces; instead you must set a key's namespace explicitly. Also, key functions have been changed and renamed.
      • The WithNamespace function has been removed. To specify a namespace in a Query, use the Query.Namespace method: go q := datastore.NewQuery("Kind").Namespace("ns")
      • All the fields of Key are exported. That means you can construct any Key with a struct literal: go k := &Key{Kind: "Kind", ID: 37, Namespace: "ns"}
      • As a result of the above, the Key methods Kind, ID, d.Name, Parent, SetParent and Namespace have been removed.
      • NewIncompleteKey has been removed, replaced by IncompleteKey. Replace go NewIncompleteKey(ctx, kind, parent) with go IncompleteKey(kind, parent) and if you do use namespaces, make sure you set the namespace on the returned key.
      • NewKey has been removed, replaced by NameKey and IDKey. Replace go NewKey(ctx, kind, name, 0, parent) NewKey(ctx, kind, "", id, parent) with go NameKey(kind, name, parent) IDKey(kind, id, parent) and if you do use namespaces, make sure you set the namespace on the returned key.
      • The Done variable has been removed. Replace datastore.Done with iterator.Done, from the package
      • The Client.Close method will have a return type of error. It will return the result of closing the underlying gRPC connection.
      • See the announcement for more details.
  • v0.4.0 Changes

    • bigquery: -NewGCSReference is now a function, not a method on Client.

      • Table.LoaderFrom now accepts a ReaderSource, enabling loading data into a table from a file or any io.Reader.
      • Client.Table and Client.OpenTable have been removed. Replace go client.OpenTable("project", "dataset", "table") with go client.DatasetInProject("project", "dataset").Table("table")
      • Client.CreateTable has been removed. Replace go client.CreateTable(ctx, "project", "dataset", "table") with go client.DatasetInProject("project", "dataset").Table("table").Create(ctx)
      • Dataset.ListTables have been replaced with Dataset.Tables. Replace go tables, err := ds.ListTables(ctx) with go it := ds.Tables(ctx) for { table, err := it.Next() if err == iterator.Done { break } if err != nil { // TODO: Handle error. } // TODO: use table. }
      • Client.Read has been replaced with Job.Read, Table.Read and Query.Read. Replace go it, err := client.Read(ctx, job) with go it, err := job.Read(ctx) and similarly for reading from tables or queries.
      • The iterator returned from the Read methods is now named RowIterator. Its behavior is closer to the other iterators in these libraries. It no longer supports the Schema method; see the next item. Replace go for it.Next(ctx) { var vals ValueList if err := it.Get(&vals); err != nil { // TODO: Handle error. } // TODO: use vals. } if err := it.Err(); err != nil { // TODO: Handle error. } with for { var vals ValueList err := it.Next(&vals) if err == iterator.Done { break } if err != nil { // TODO: Handle error. } // TODO: use vals. } Instead of the RecordsPerRequest(n) option, write go it.PageInfo().MaxSize = n Instead of the StartIndex(i) option, write go it.StartIndex = i
      • ValueLoader.Load now takes a Schema in addition to a slice of Values. Replace go func (vl *myValueLoader) Load(v []bigquery.Value) with go func (vl *myValueLoader) Load(v []bigquery.Value, s bigquery.Schema)
      • Table.Patch is replace by Table.Update. Replace go p := table.Patch() p.Description("new description") metadata, err := p.Apply(ctx) with go metadata, err := table.Update(ctx, bigquery.TableMetadataToUpdate{ Description: "new description", })
      • Client.Copy is replaced by separate methods for each of its four functions. All options have been replaced by struct fields.
      • To load data from Google Cloud Storage into a table, use Table.LoaderFrom.


        client.Copy(ctx, table, gcsRef)



      Instead of passing options to Copy, set fields on the Loader:

        loader := table.LoaderFrom(gcsRef)
        loader.WriteDisposition = bigquery.WriteTruncate
      • To extract data from a table into Google Cloud Storage, use Table.ExtractorTo. Set fields on the returned Extractor instead of passing options.


        client.Copy(ctx, gcsRef, table)


      • To copy data into a table from one or more other tables, use Table.CopierFrom. Set fields on the returned Copier instead of passing options.


        client.Copy(ctx, dstTable, srcTable)


      • To start a query job, create a Query and call its Run method. Set fields on the query instead of passing options.


        client.Copy(ctx, table, query)


      • Table.NewUploader has been renamed to Table.Uploader. Instead of options, configure an Uploader by setting its fields. Replace go u := table.NewUploader(bigquery.UploadIgnoreUnknownValues()) with go u := table.NewUploader(bigquery.UploadIgnoreUnknownValues()) u.IgnoreUnknownValues = true
    • ๐Ÿ“ฆ pubsub: remove pubsub.Done. Use iterator.Done instead, where iterator is the package

  • v0.3.0 Changes

    November 11, 2020
    • storage:

      • AdminClient replaced by methods on Client. Replace go adminClient.CreateBucket(ctx, bucketName, attrs) with go client.Bucket(bucketName).Create(ctx, projectID, attrs)
      • BucketHandle.List replaced by BucketHandle.Objects. Replace go for query != nil { objs, err := bucket.List(d.ctx, query) if err != nil { ... } query = objs.Next for _, obj := range objs.Results { fmt.Println(obj) } } with go iter := bucket.Objects(d.ctx, query) for { obj, err := iter.Next() if err == iterator.Done { break } if err != nil { ... } fmt.Println(obj) } (The iterator package is at

      Replace Query.Cursor with ObjectIterator.PageInfo().Token.

      Replace Query.MaxResults with ObjectIterator.PageInfo().MaxSize.

      • ObjectHandle.CopyTo replaced by ObjectHandle.CopierFrom. Replace go attrs, err := src.CopyTo(ctx, dst, nil) with go attrs, err := dst.CopierFrom(src).Run(ctx)


        attrs, err := src.CopyTo(ctx, dst, &storage.ObjectAttrs{ContextType: "text/html"})


        c := dst.CopierFrom(src)
        c.ContextType = "text/html"
        attrs, err := c.Run(ctx)
      • ObjectHandle.ComposeFrom replaced by ObjectHandle.ComposerFrom. Replace go attrs, err := dst.ComposeFrom(ctx, []*storage.ObjectHandle{src1, src2}, nil) with go attrs, err := dst.ComposerFrom(src1, src2).Run(ctx)
      • ObjectHandle.Update's ObjectAttrs argument replaced by ObjectAttrsToUpdate. Replace go attrs, err := obj.Update(ctx, &storage.ObjectAttrs{ContextType: "text/html"}) with go attrs, err := obj.Update(ctx, storage.ObjectAttrsToUpdate{ContextType: "text/html"})
      • ObjectHandle.WithConditions replaced by ObjectHandle.If. Replace go obj.WithConditions(storage.Generation(gen), storage.IfMetaGenerationMatch(mgen)) with go obj.Generation(gen).If(storage.Conditions{MetagenerationMatch: mgen})




        obj.If(storage.Conditions{DoesNotExist: true})
      • storage.Done replaced by iterator.Done (from package
