EventStoreDB is an industrial-strength database technology used for event-sourcing. It is open source and runs on most platforms or as SaaS in Event Store Cloud.
This repository provides practical samples that demonstrate features of EventStoreDB and its client SDKs.
Common operations and samples are in the client repositories
Feel free to create a GitHub issue if you have any questions or request for more explanation or samples.
