SQL Stream Store

⚠️ These libraries are no longer actively maintained.

A stream store library for .NET that specifically targets SQL based implementations. Primarily used to implement Event Sourced applications.

Package	Install
SqlStreamStore (includes in-memory version for behaviour testing)
MS SQL Server / Azure SQL Database
PostgreSQL / AWS Aurora
MySQL / AWS Aurora
Sqlite	up for grabs
HTTP Wrapper API	On CI Feed
Schema Creation Script Tool

CI Packages available on Feedz.

Design considerations:

• Designed to only ever support RDMBS/SQL implementations.
• Subscriptions are eventually consistent.
• API is influenced by (but not compatible with) EventStore.
• Async only.
• JSON only event and metadata payloads (usually just a string / varchar / etc).
• No support for System.Transaction, enforcing the concept of the stream as the consistency and transaction boundary.

Building

Building requires Docker. Solution and tests are run on a linux container with .NET Core leveraging SQL Server, Postgres and MySQL as sibling containers.

• Windows, run .\build.cmd
• Linux, run ./build.sh

Note: build does not work via WSL.
