It acts a a conversion layer between any [EventStoreDB](https://www.eventstore.com) compatible client and the SQL language.\n\n## Why EventStormDB?\n\nEvent Store is a purpose-built database, offering advanced stream analysis and querying features that are otherwise difficult to replicate with SQL or a data analysis pipeline. Its [Projection Subsystem](https://developers.eventstore.com/server/v5/projections.html#introduction-to-projections) provides the ability to pipe existing streams through transformation functions that write other streams that which can be then consumed directly or trigger further transformations.\n\nHowever, due to its use-case specific nature, it is not likely for a real world application to completely rely on Event Store. \n\nOn the countrary, Postgres is a general purpose SQL database, which is developer friendly and battle-tested.\nIt ships with a miryad of community developed extensions and it is well-supported by major cloud providers like Amazon Web Services and Google Cloud Platform.\n\nThat is why implementing a simple eventsourcing layer on the top of PostgreSQL is a common and cheaper choice with respect to the cost of switching and maintain an EventStoreDB cluster.\n\n**EventStorm** was born to provide the full power of EventStore stream processing primitives to PostgreSQL users without additional dependencies.\nIt is meant to be a replacement for EventStore expecially in following scenarios:\n\n- You are aready running PostgreSQL, but want to exploit the power of EventStore subscriptions and/or projections;\n- You want to estimate the impact of migrating to EventStoreDB.\n\nYou should rather use **EventStoreDB** if:\n\n- you need a distributed database;\n- you have to deal with tremendous write workloads which cannot be handled by PostgreSQL (EventStoreDB makes use of append-only log).\n\n## Contact\nStefano Scafiti @ostafen\n\n## License\nEventStormDB source code is available under the **MIT License**.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fostafen%2Feventstorm","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fostafen%2Feventstorm","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fostafen%2Feventstorm/lists"}
