# Cellar | ||
|
||
Cellar is the append-only storage backend in Go designed for the analytical | ||
workloads. It replaces [geyser-net](https://github.com/abdullin/geyser-net). | ||
|
||
Core features: | ||
|
||
- events are automatically split into the chunks; | ||
- chunks are encrypted and compressed; | ||
- designed for batching operations (high throughput); | ||
- supports single writer and multiple concurrent readers; | ||
- store secondary indexes, lookups in the metadata DB. | ||
|
||
This storage takes ideas from the [Message Vault](https://github.com/abdullin/messageVault), | ||
which was based on the ideas of Kafka and append-only storage in [Lokad.CQRS](https://github.com/abdullin/lokad-cqrs) | ||
|
||
Analytical pipeline on top of this library was deployed at | ||
HappyPancake to run real-time aggregation and long-term data analysis | ||
on the largest social website in Sweden. You can read more about it in | ||
[Real-time Analytics with Go and LMDB](https://abdullin.com/bitgn/real-time-analytics/). | ||
