Xephon-K is a time series database with multiple backends. 

It's a playground for comparing modern TSDB design and implementation.

It is not for production use, but it can show you simplified implementation of popular TSDBs. 

A detailed (but not well organized) survey can be found in [doc/survey](doc/survey).

- status: Under major rewrite, after libtsdb-go is stable and benchhub is usable (again), all old code are moved to [_legacy](_legacy)

- [Slide: Xephon-K A Time Series Database with multiple backends](http://www.slideshare.net/ssuser7e134a/xephon-k-a-time-series-database-with-multiple-backends)

- [Survey on existing Cassandra based TSDBs (now include TSDB with other backends)](doc/survey)

## Supported backend

- In Memory

- Local disk, modeled after [InfluxDB](https://github.com/influxdata/influxdb)

- Cassandra, modeled after [KairosDB](https://github.com/kairosdb/kairosdb), but the partitioned schema is not implemented

Following are some backends I plan to implement in the future

- RocksDB

- Redis

- MySQL, modeled after VividCortex

- S3 + Dynamo, modeled after [weaveworks' cortex](https://github.com/weaveworks/cortex/)

- Awesome list [awesome-time-series-database](https://github.com/xephonhq/awesome-time-series-database)

- Benchmark suite [xephon-b](https://github.com/xephonhq/xephon-b) Might still compile

## About

- Xephon comes from animation [RahXephon](https://en.wikipedia.org/wiki/RahXephon), which is chosen for [Xephon-B](https://github.com/xephonhq/xephon-b)

- K comes from KairosDB because this project is originally modeled after KairosDB, which is also the first TSDB I have used in production.
