Why M3?

M3, a metrics platform, and M3DB, a distributed time series database, were developed at Uber out of necessity. After using what was available as open source and finding we were unable to use them at our scale due to issues with their reliability, cost and operationally intensive nature we built our own metrics platform piece by piece. We used our experience to help us build a native distributed time series database, a highly dynamic and performant aggregation service, query engine and other supporting infrastructure.

Cluster Management

Out of the box support for handling multiple clusters, built on top of etcd

Replicated

Built-in replication with configurable durability and read consistency for your needs

Customizable Consistency

Reads and writes can be set to quorum or lower or higher depending on durability preferences

Prometheus Integration

M3DB can act as the long term storage for Prometheus using remote read/write endpoints

Highly Compressed

Efficient compression algorithm inspired by Gorilla TSZ, configurable as lossless or lossy

Arbitrary Time Precision

Configurable precision from seconds to nanoseconds, with the ability to switch precision with any write

Out of order writes

Handles out of order writes seamlessly, only limited by the size of the configured database block size

Fully open source

All features are fully available and open source. Any contributions are welcome!
