snapshotstore/sql/v0.1.0

SQL snapshot store building on the Snapshot struct and the SnapshotStore interface from the core/v0.4.0 module.

core/v0.4.0

Added Snapshot support to the core module. This include the Snapshot struct:

// Snapshot holds current state of an aggregate
type Snapshot struct {
	ID            string
	Type          string
	Version       Version
	GlobalVersion Version
	State         []byte
}

And the SnapShotStore interface to be implemented by different storage backends.

// SnapshotStore expose the methods a snapshot store must uphold
type SnapshotStore interface {
	Save(snapshot Snapshot) error
	Get(ctx context.Context, id, aggregateType string) (Snapshot, error)
}

v0.3.0

Use core/v0.3.0

eventstore/sql/v0.3.0

Use core/v0.3.0

eventstore/esdb/v0.3.0

Use core/v0.3.0

eventstore/bbolt/v0.3.0

Use core/v0.3.0

core/v0.3.0

Change the Iterator interface

type Iterator interface {
 	Next() bool
 	Value() (Event, error)
 	Close()
 }

It's easier to signal when the there is no more events to return with the Next() method. Before that was signaled with errors.

Removed the errors that was used to signal if there was no events to fetch or no more events to fetch.

// ErrNoEvents when there is no events to get
var ErrNoEvents = errors.New("no events")

// ErrNoMoreEvents when iterator has no more events to deliver
var ErrNoMoreEvents = errors.New("no more events")

v0.2.0

• Start use v0.2.0 of the core module.
• Return the new eventsourcing.ErrConcurrently error when the event store return the core.ErrConcurrently error.
• Wrap event store internal error.

eventstore/sql/v0.2.1

Same as eventstore/sql/v0.2.0 but with correct version format.

eventstore/sql/v0.2.0

• Start use v0.2.0 of the core module.
• Stop using the event validator function from the core module.
• Return the core.ErrConcurrently error when saving events that are out of order.
