A time series database prototype with multiple backends

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.

• Slide: Xephon-K A Time Series Database with multiple backends
• Survey on existing Cassandra based TSDBs (now include TSDB with other backends)

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

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.
