March 17, 2017
Breaking Pubsub changes.
February 14, 2017
Release of a client library for Spanner. See the blog post.
Note that although the Spanner service is beta, the Go client library is alpha.
December 12, 2016
Beta release of BigQuery, DataStore, Logging and Storage. See the blog post.
Also, BigQuery now supports structs. Read a row directly into a struct with
RowIterator.Next
, and upload a row directly from a struct with Uploader.Put
.
You can also use field tags. See the [package documentation][cloud-bigquery-ref]
for details.
December 5, 2016
More changes to BigQuery:
The ValueList
type was removed. It is no longer necessary. Instead of
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.
The SQL types DATE, TIME and DATETIME are now supported. They correspond to
the Date
, Time
and DateTime
types in the new cloud.google.com/go/civil
package.
November 17, 2016
Change to BigQuery: values from INTEGER columns will now be returned as int64, not int. This will avoid errors arising from large values on 32-bit systems.
November 8, 2016
New datastore feature: datastore now encodes your nested Go structs 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.
type State struct {
Cities []struct{
Populations []int
}
}
See the announcement for more details.
November 8, 2016
Breaking changes to datastore: 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:
q := datastore.NewQuery("Kind").Namespace("ns")
All the fields of Key are exported. That means you can construct any Key with a struct literal:
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
NewIncompleteKey(ctx, kind, parent)
with
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
NewKey(ctx, kind, name, 0, parent)
NewKey(ctx, kind, "", id, parent)
with
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 google.golang.org/api/iterator
.
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.
October 27, 2016
Breaking change to bigquery: NewGCSReference
is now a function,
not a method on Client
.
New bigquery feature: Table.LoaderFrom
now accepts a ReaderSource
, enabling
loading data into a table from a file or any io.Reader
.
October 21, 2016
Breaking change to pubsub: removed pubsub.Done
.
Use iterator.Done
instead, where iterator
is the package
google.golang.org/api/iterator
.
October 19, 2016
Breaking changes to cloud.google.com/go/bigquery:
Client.Table and Client.OpenTable have been removed. Replace
client.OpenTable("project", "dataset", "table")
with
client.DatasetInProject("project", "dataset").Table("table")
Client.CreateTable has been removed. Replace
client.CreateTable(ctx, "project", "dataset", "table")
with
client.DatasetInProject("project", "dataset").Table("table").Create(ctx)
Dataset.ListTables have been replaced with Dataset.Tables. Replace
tables, err := ds.ListTables(ctx)
with
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
it, err := client.Read(ctx, job)
with
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
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
it.PageInfo().MaxSize = n
Instead of the StartIndex(i)
option, write
it.StartIndex = i
ValueLoader.Load now takes a Schema in addition to a slice of Values. Replace
func (vl *myValueLoader) Load(v []bigquery.Value)
with
func (vl *myValueLoader) Load(v []bigquery.Value, s bigquery.Schema)
Table.Patch is replace by Table.Update. Replace
p := table.Patch()
p.Description("new description")
metadata, err := p.Apply(ctx)
with
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.
Replace
client.Copy(ctx, table, gcsRef)
with
table.LoaderFrom(gcsRef).Run(ctx)
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.
Replace
client.Copy(ctx, gcsRef, table)
with
table.ExtractorTo(gcsRef).Run(ctx)
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.
Replace
client.Copy(ctx, dstTable, srcTable)
with
dst.Table.CopierFrom(srcTable).Run(ctx)
To start a query job, create a Query and call its Run method. Set fields on the query instead of passing options.
Replace
client.Copy(ctx, table, query)
with
query.Run(ctx)
Table.NewUploader has been renamed to Table.Uploader. Instead of options, configure an Uploader by setting its fields. Replace
u := table.NewUploader(bigquery.UploadIgnoreUnknownValues())
with
u := table.NewUploader(bigquery.UploadIgnoreUnknownValues())
u.IgnoreUnknownValues = true
October 10, 2016
Breaking changes to cloud.google.com/go/storage:
AdminClient replaced by methods on Client. Replace
adminClient.CreateBucket(ctx, bucketName, attrs)
with
client.Bucket(bucketName).Create(ctx, projectID, attrs)
BucketHandle.List replaced by BucketHandle.Objects. Replace
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
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 google.golang.org/api/iterator
.)
Replace Query.Cursor
with ObjectIterator.PageInfo().Token
.
Replace Query.MaxResults
with ObjectIterator.PageInfo().MaxSize
.
ObjectHandle.CopyTo replaced by ObjectHandle.CopierFrom. Replace
attrs, err := src.CopyTo(ctx, dst, nil)
with
attrs, err := dst.CopierFrom(src).Run(ctx)
Replace
attrs, err := src.CopyTo(ctx, dst, &storage.ObjectAttrs{ContextType: "text/html"})
with
c := dst.CopierFrom(src)
c.ContextType = "text/html"
attrs, err := c.Run(ctx)
ObjectHandle.ComposeFrom replaced by ObjectHandle.ComposerFrom. Replace
attrs, err := dst.ComposeFrom(ctx, []*storage.ObjectHandle{src1, src2}, nil)
with
attrs, err := dst.ComposerFrom(src1, src2).Run(ctx)
ObjectHandle.Update’s ObjectAttrs argument replaced by ObjectAttrsToUpdate. Replace
attrs, err := obj.Update(ctx, &storage.ObjectAttrs{ContextType: "text/html"})
with
attrs, err := obj.Update(ctx, storage.ObjectAttrsToUpdate{ContextType: "text/html"})
ObjectHandle.WithConditions replaced by ObjectHandle.If. Replace
obj.WithConditions(storage.Generation(gen), storage.IfMetaGenerationMatch(mgen))
with
obj.Generation(gen).If(storage.Conditions{MetagenerationMatch: mgen})
Replace
obj.WithConditions(storage.IfGenerationMatch(0))
with
obj.If(storage.Conditions{DoesNotExist: true})
storage.Done
replaced by iterator.Done
(from package google.golang.org/api/iterator
).
