README ¶

Xephon-K

Xephon-K is a time series database with multiple backends. It's a playground for comparing modern TSDB design and implementation with benchmarks. It is not for production use, but it can show you the internal and trade-off of many TSDBs. A detailed (but not well organized) survey can be found in doc/survey.

Supported backends

In Memory
Local disk, modeled after InfluxDB
Cassandra, modeled after 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

Awesome list awesome-time-series-database
Proxy tsdb-proxy Not active, partially merged into Xephon-K
Benchmark suite xephon-b Not active, partially merged into Xephon-K

About the name

Xephon comes from animation RahXephon, which is chosen for Xephon-B
K comes from KairosDB since this project is originally modeled after KairosDB, which is also the first TSDB I have used in production.
