Design

Streamstone is a thin library layer on top of Windows Azure Table Storage. It implements the low-level mechanics for dealing with event streams, while all heavy lifting is done by the underlying provider.

  • The API is stateless and all exposed objects are immutable once constructed.
  • Streamstone does not dictate the payload serialization protocol, so you are free to choose any protocol you want.
  • Optimistic concurrency is implemented by always including a stream header entity with every write, making it impossible to append to a stream without first having the latest Etag.
  • Duplicate event detection is done by automatically creating an additional entity for every event, with RowKey set to a unique identifier of the source event (consistent secondary index).
