Functions

func DeletePrefix added in v1.7.0 

func DeletePrefix(ctx context.Context, bkt objstore.Bucket, prefix string, logger log.Logger) (int, error)

DeletePrefix removes all objects with given prefix, recursively. It returns number of deleted objects. If deletion of any object fails, it returns error and stops.

func NewClient 

func NewClient(ctx context.Context, cfg Config, name string, logger log.Logger, reg prometheus.Registerer) (client objstore.Bucket, err error)

NewClient creates a new bucket client based on the configured backend

func NewUserBucketClient 

func NewUserBucketClient(userID string, bucket objstore.Bucket) *UserBucketClient

func (*UserBucketClient) Close 

func (b *UserBucketClient) Close() error

Close implements io.Closer

func (*UserBucketClient) Delete 

func (b *UserBucketClient) Delete(ctx context.Context, name string) error

Delete removes the object with the given name.

func (*UserBucketClient) Name

func (*UserBucketClient) WithExpectedErrs 

func (b *UserBucketClient) WithExpectedErrs(fn objstore.IsOpFailureExpectedFunc) objstore.Bucket

WithExpectedErrs allows to specify a filter that marks certain errors as expected, so it will not increment thanos_objstore_bucket_operation_failures_total metric.

type UserBucketReaderClient 

type UserBucketReaderClient struct {
	// contains filtered or unexported fields
}

UserBucketReaderClient is a wrapper around a objstore.BucketReader that reads from user-specific subfolder.
